most dad i've met like physical graffiti the best
and my dad tells me he never could really get into zeppelin
@twigby - have you ever seen the dvd for "the song remains the same"
my dad was at the concerts the filmed those at. he loves him some zeppelin. he also says he never ever smoked pot. and knowing him, it isn't naive at all to believe him.

although, it might be some other led zeppelin album.
