This comically inept singer looks like a coked-up CPA trying to channel Screaming Lord Sutch. He rivals Mike Love in creepiness. If real, I’m guessing this was an open mic thing.
And all of you who ever played in a band can ‘fess up: you either struck or wanted to strike whoever did most of the singing with a guitar, bass, mic stand, cymbal stand, floor tom, etc. Or said, “go ahead and grab the mic” when you knew it wasn’t grounded.
And if you did most of the singing, you probably deserved it.
