I think it would be cool to be in a band that covers popular songs, only switching instruments with vocals, and perhaps even vocals with instruments. Instead of the bass player playing the bass, he'd use his voice to hum or bop the bass lines, and the drummer would do like a boombox or something, and the guitarist would sing all the chords. kinda like an a cappella/acoustic thing. I think i might try and record a song like that with me doing all the parts. Requests?
