I suppose every guitarist has his/her favourite riffs and thingies he/she does to warm up before turning to their regular stuff. Whenever I take out my guitar at bandrehearsals or gigs I do some fingerpicking from "The Actor" and, when I've connected my electric guitar (335, of course :) ), I always start off with "Lovely to see you". Usually drives the rest of the band insane, really. Turning the overdrive up and loud and playing something from "The story in your eyes" also
gets you all nice and warmed up !
