We do theme cakes for b'days. Should've seen our banjo player when i made him a pony sized banjo cake. Was priceless. Anyway, musicians are the easiest people in the world to get little things for. You never have enough: Strings, picks, batteries for the tuner, straps, dulcimer hammers, string shine, i could go on and on and on. And it would appear that i have done so! And of course, having the gang over to jam, with a bluegrass rendition of Happy b'day to you, is most effective.
