Thanks, glad you enjoyed it.
As far as Meddle goes, it has the same line-up as Dark Side of the Moon and most of the classic albums. Aside from Roger quitting and Rick's firing and rehiring, the band's line-up only changed once. That change took place in 1968 when fthe band's lead guitarist and primary lyricist Syd Barrett was replaced with guitarist David Gilmour due to Barrett's self-destructive struggle with LSD and other drugs. But yeah, Meddle kicks ass. Props to the band for including "Echoes" on their greatest hits album, but boo to them for editing it down.
