Okay, kinda a grim and morbid one for a Sunday morning, but what song would you like to be buried to? You know, the song you would want them to play as they haul your sorry oak-panelled ass down through the church (etc.) for the last time.
Personally, I don't know. I'm going to go with 'Crystal Ship' by The Doors. Partly because it's pretty fucking mean and trippy, and partly because it's not too long. As in life, length matters a good deal in this accompaniment to the final journey: asking for 'Shine On You Crazy Diamond' or the long version of 'Free Bird' will just be plain rude to your guests.
And you don't want to piss them off, do you?
Check it out scumbags: Crystal Ship for those of you saying 'which one is that again?' Man, I love this shit.
