In my 50's, still doing 40+ gigs per year, I'm just about good enough to play the covers we do convincingly. Thankfully the live track we have just put on our website comes badly mixed under the title "bassist seen and not heard"
Frustrations? Would love to do a few gigs with a prog band. Would love to set up a " rock and roll" covers band, everything from Haley through Beatles, T Rex, Quo, Shaky to Paulo Nutini.
Excuses? Time and effort, ie not making either available.
And I haven't been arsed writing my own stuff for a decade.
Who's a miserable old Hector then?
