The only thing I miss on stage is the falsetto. Barry Gibb
I used to do this big rant at the end of some gigs with Ben Folds Five. The band broke into this big heavy metal thing and I started as a joke to scream in a heavy metal falsetto. I found myself saying things like: Feel my pain, I am white, feel my pain. Ben Folds
From then on in, me and Sonny started makin' records. My first records, Sonny was backin' me up. Sonny wasn't singin' natural at the time; he was singin' falsetto. Brownie McGhee
