That (wedding band bassist) is a little bit more than I'd aspire to at the moment. I'm only a hobby bassist remember.
I can (almost) appreciate how much of a job that would be in high season. Still, if I got the bug and a few successful bookings as a singing bassist, who knows? I might actually build the stamina for such work. It imagine that it would help build a repertoire and round off the skills more quickly than doing pub gigs.
I'm sure that Dave has reasons of his own for not wanting it.
