Sixty today is like 40 a generation ago--there's still plenty of time to do a reboot career-wise if you're so inclined. I do wonder though, as rootabaga implied, about the area of music sales being something viable these days. Could you perhaps expand on it a little and tell us exactly what would be involved?
Anyway, generally speaking, if you're 60+ you're still considered young-ish in today's world, so go for it!
