What they would do.

John: *would immediately get flustered and start screaming at the TV.*

Paul: *would be jamming like crazy.*

George: *would slide across the floor on his knees doing a guitar solo.*

Ringo: *would be appalled by how different it was from actual drumming.*

What they would say.

John: What do you mean three stars?!? That was worth five!!! So you have any idea how hard I worked getting that guitar solo "fab"? I deserve better!!! If you won't give me the stars I deserve . . . I'm quitting, TV! That's right. You heard me! D-O-N-E, done.

Paul: You go, virtual me! Yeah! Nail that bass! *sighs dreamily while gazing at his video-game-self.* We have so much in common.

George: *singing* Here comes the sun. *wails on the guitar, getting a perfect solo, all while spinning around in circles on his side on the floor.*

Ringo: What is this??? This isn't anything like actual drumming!!! How am I supposed to work with this? And WHO IN THE RIGHT MIND DECIDED TO GIVE VIRTUAL RINGO BROWN EYES?!? My eyes are blue, thank you. Can you not tell, game-makers???

(Ringo having brown eyes on Beatles Rock Band annoys me the most 😒 )
