I'd like to hear that stuff sometime. "Wish You Were Here" is great.
"Meddle" is an easy one to find and definitely worth a listen. Several listens. Addictive, like so much of their music. Its not as polished as "Dark Side" but not nearly as experimental as their earlier stuff (although the song "Echoes" is 23 minutes long and most of "Seamus" is sung by a dog). They just don't make music like that anymore.
Since George Harrison had to pay the Chiffons (I think that's who it was) for stealing their melody for his My Sweet "lxrd", why haven't Pink Floyd sued Phil Collins for that part of the chorus of Don't You Wish it would Rain (I think that's the title)?
