I played for 10 yrs in a 50,60,s doo wop band and retired, finally. They call me up to sub for their drummer, no problem, I thought. Same show, tunes, schtick, etc. Bass player says to me "those fast songs seem a little slower than usual". I say "are you serious" as the sweat is pouring off my face.I think its happening, I'm slowing down. Anyone else?
