mmmm what a novel and new topic :-) i wonder this gets less comments than the non positive ones ?
for me its playing the music you love and people coming up to you at the end and saying they had a brilliant night, that does it for me every time
if someone comes up to say youre a brilliant player its lovely to hear, not in a big headed way, more along the lines of all those years of hard work and practice are obvious to someone out there , and theyve made an effort to come and tell you personally, nice that :-)
and gig banter, fun taking the mick out of each other in the band , but some fun banter with an audience member can be very funny :-)
