WHY DO LOVE SONGS HAVE BACKUP SINGERS?

Think about it. Why is it always some guy and all his friends singing to you girl?

Guy: I'm the only one who can do it to you right, baby
His drinking buddies: Ooh-ooh, oh yes I am the only one.
Guy: I'm gonna stick it in you and be the only one!
Some dudes he met one time: I hope there's room enough for us...

"Because your kiss, your kiss is on my list. Because your kiss is what I miss, when I turn out the lights."

That's two guys. What, do they round up every guy who's been inside that and have him sing the same song?

"Okay, you're the loudest, you sing lead. Oates, you do the backing vocals."
