One song I have to admit I do enjoy (although really I shouldn't) is T-Bone from the Re-ac-tor album.
For those of you unfamiliar with this song - understandable given that Re-ac-tor is not one of Neil's better known or more acclaimed albums - the song is over 9 minutes in length and combines a guitar jam with the following lyrics, among the deepest every penned: 'Got mashed potatoes' and 'Ain't got no T-Bone', repeated several times each throughout the song and set against a repetitive guitar riff. By all accounts this song should be absolutely terrible, but I love it! I guess it's my sick and twisted sense of humour showing again.
The Youtube video of it I've been watching has a picture of Neil with the quote 'You don't make a 10 minute song about having mashed potatoes and not having T-bone without making a few enemies'.
