ayt .. haha .. reading your answers is really funny .. haha .. i know a lot of people hates the jo bros .. i used to hate them too, very much .. but i don't know what happened to me and changed my mind ..
but i think, collaboration with the jo bros would never happen .. i also don't think it's healthy for david to sing the jo bros genre .. but IF i would be lucky enough and that would happen, i would LOOOOVE IT! =)
I think honestly it'd be a unique medley of voices. I know a lot of people are anti JoBro. After seeing them in person I'm impressed. I think it'd be a better duet (quartet?) than the Hannah Montana song.
