Just needs a little ‘rehearsal time’ and a set list.
Saw him live in concert several times from 1994-2001.
Even then he would sit down for the show and either sing, or play guitar, but not do both at the same time. He’d play a song halfway through as an instrumental and come in with the vocal, or lead with the vocal and pick some notes at the bridge.
James Brown was a singer, songwriter, band leader, and a musician (although I only ever saw him play music in his final tour out of 3 decades I saw him in).
At a point, the band behind BB and BB singing is part of the show.
The final time I saw James Brown, it was the smallest band I’d seen him with, and he played a 2 song keyboard tribute to Ray Charles (who’d died earlier that year) as well as keys on a few other songs. He’d slowed down a bit over previous times I’d seen him, but he never left the stage to take a break or even took a sip of water.
Hardest working man in show biz. Hard title to beat.
