With no guitar in sight I think my favourite intros are (Don't shoot me) both by OMD... " Messages" (the single/live way not the album")and "Electricity"
Last time I saw OMD was one of the very first gigs at Symphony Hall in Brum in 1991, ok wasn't the "proper" OMD .. started with a new song nobody knew, everybody sat and listened and applauded politely... Andy McLuskey looks all around the hall, says " Just because it's a posh venue doesn't mean you have to behave".. keyboard player starts plinking out "Messages" and nobody sat down for the rest of the night
