Found today: Laura Nyro - "Sweet Blindness / Stoned Soul Picnic", a promo-only coupling from her Eli LP with no catalog number and a unique color scheme, at first glance I thought it was a children's record!
Stealers Wheel "Everyone's Agreed That Everything Will Turn Out Fine" 45: The other side is Mono. The single version is a different recording from the album version. Sadly, due to the 2008 UMG fire, the master tape for this version is probably lost forever.
Not sure if this note was actually written by David Baerwald but the guy I bought this from at a record show often has signed items. If it's legit, fine. If not, that's OK too. It's just an added wrinkle to the item and it wasn't expensive:
