>The characters ITT go on stage to sing their favorite song.
>What do they sing?
>Which go to perform a duo or a group song?

>Ziggy sings Starman
>Everyone takes a drink in tribute to the Thin White Duke
>A single tear rolls down every cheek in the bar, with Ziggy oblivious to the sorrow he has caused.

>"Thanks Mr. Stardust for your rendition of Starman," says the MC wiping his tears away. "I know this may be hard on most of you, but the show must go on!" and just like that his demeanor goes back to happy.
>"Coming on next we have Aryanne, Luftkrieg and Franziska doing a group song!"
>Three blondes go on stage and a merry tune begins playing, https://www.youtube.com/watch?v=pVJFmcsq3-k, but you don't pay much attention.
>"That really got the mood down," says a guy looking just like you sitting by your right side. "You think he did it on purpose?"
>"Nah man. My boi Ziggy just doesn't know any better." answers a greener version of yourself.
"He is right, he has the best intentions, but you know..."
>"Nigga just doesn't have a clue."
>"Come on, he can't be that clueless."
>Oh no he didn't.
>"You don't believe this shit?" you know you can't stop this from happening, but you at least hope he... "HEY! SATIPO! COME SIT HERE!"
>... doesn't make a scene.
>Ziggy comes to the table.
>"Hey Anon, I mean KANYE, " he says as he greets the other you in an elaborated fist bump, "and [ANONYMOUS] too, it sure has been a while," he says trying to shake your hand, his phasing through yours. "I keep forgeting about that."
>Just now he takes notice of the third man in the table.
>"I don't think we've been introduced. I'm Ziggy Stardust, nice to meet you Mr..."
>"Anonymous," says the other you in an unbelieving tone "so I take you know these guys?"
>"I sure do!"
>"How did that happen?"
>"Let me tell you, " begins the other Anon, "I was having a fancy ass dinner with my girl, go to the bathroom for a second and find this nigga humping and shoving his meat on her mouth!" he concludes the story laughing ans slapping the table getting the attention of several patrons.
>"Yeah, I was worried I wasn't doing it right, but she thankfully spat it out in the end."
>The Anon on your right seems disgusted.
"It probably wasn't what you are thinking." you whisper to him.

>"And now, we have Maud, Limestone, Marble and Pinkie doing another group song!" announces the MC as three mares take the stage.
>The song begins to play, https://www.youtube.com/watch?v=WxNvdQCbLco, but you still don't pay attention.
>"What about our ghostly friend here?" asks the Anon on your right.
>"Well, I don't really know the details myself, but he was my stand for a while."
>"Hold on. What do you mean by "he was your stand"?
"Somehow I became stranded from my user and ended up bound to him."
>"Shit son, that can happen?"
"I wasn't the only one from what I heard. But that problem has already been solved." you conclude not wanting to remember that incident.
>"Now that you mention it, I don't remember how it was solved..." says Ziggy, clearly trying his best to remeber.
"Don't worry about it. I got back to my user and that is all that matters."
>"Ok. Where is she by the way? I wanted to meet her."
>You take a look at the drunken mare passed out below the table.
"She is... in the bathroom."
>"Oh, give her my regards later then." He says with a smile while looking in awe at the Pies on stage. "Those animatronics look so lifelike..."
>"That's 'cause they are..."
>You signal the Anon to stop.
"Don't even try. He won't get it."
>He reluctantly agrees.
>The song finishes, and everyone claps at the group of mares.
>Ziggy seems to be really into it.
>"You seem to be having a blast."
>"I sure am."
>"Even though you made everyone so sad with your song."
>Shoot. What is he trying to do?
>"Dude, I told you Ziggy didn't mean to do that."
>"It's ok. I did notice what happened." says Ziggy.
>He did?
>"You did?"
>"Yeah, I could see it in everyones eyes, I..."
>Wait for it...
>"... must be a really bad singer." says Ziggy in a serious voice.
>"Whu, no!" says Anon, his voice raising a bit "everyone got sad because you reminded them of Bowie!"
>"Who?"
>" The Thin White Duke! Major Tom! Glam Rock impersonated! David Fucking Bowie!"
>"Oh... I don't know who that is"

>You didn't think it was possible, but ?Tom's Diner? became quiet.
>Everyone, and surprisingly everypony, are whispering among themselves.
>"Is something wrong?" he asks, clearly not getting in what situation he is in.
>"Ziggy, my man, " Anon begins to speak, clearly trying to find the right words "are you really saying that you, from all the people in the multiverse, don't know David Bowie?"
>"Is it that hard to believe?"
>"But... your stand..."
>"Oh, I found that odd too. Someone had used my stand's name for a song."
>...
>"Do you think that could happen to someone else?"
>The Anons are left speechless.
>"Oh well, I guess it doesn't really matter." he gets up and leaves a tip for the waiter "I guess I'm gonna call it a night, everyone is looking at this table as if there were some Scary Monster or a Super Creep sitting in here."
>If you didn't know him, you'd have thought he was donig this on purpose.
>"See you some other time Anon, [Anon] and... uhhh you."
>And just like that he leaves 「Tom's Diner」, humming something simliar to Modern Love along the way.
"So... that was Ziggy, I guess."
>"Do you believe us now?"
>The Anon just seems frozen in place.
>"Maaaybe we should leave too."
"Good idea."
>With his help, you carry the sleeping Rainbow out of the diner, leaving him behind.

Hours later...

>"Sir, the show is over. You have to leave." says the owner.
>Anon is teleported back to his home, muttering to himself .
>"But his name is Ziggy Stardust..."
