We always try to find time to chat to people between sets, and afterwards if there is time, though usually the venue wants us to break the gear down and move out sharpish. We usually get one or two Babe Ruth fans coming along who are usually a bit star struck and ask me if it we would mind if they spoke to Jenny, but she loves to chat with her fans, sign their albums, etc.
I draw the line at buying food and drinks for the fans, though there are some exceptions, a lovely couple of 20 something girls who often come to see us. I buy them drinks and they say 'thanks, dad.'
