Vinyl pressing mistakes


Ever seen an LP with the the wrong label? I have an old LP that has a different artist/album side pressed on the b side. I listened to the a side of 'Blue Man' by Steve Khan.... flipped it over and Tim Wiesebeg/Dan Fogalberg (sp?)'Power of Gold' or some such nonsence starts playing... surprise! How common are these mistakes? Just curoius.

I have a few in my collection. Most amusing, I have an Andrew Hill record on Blue Note, B1-92051. On the jacket the title of the album is "Eternal Spirit", but on both the side 1 and side 2 labels it says "Internal Spirit". The whole Blue Note thing went to hell when Capitol took over. Just listen to the tin can sound of the latest Jason Moran CD. My Dionne Warwick box set also comes to mind. One of the records has two side one label on it. These things come up from time to time.
I have a mis-labeled Arista Grateful Dead - Histroic Dead album with an Alan Parson's Project label on sides 3/4 of the album (vinyl pressing is still GD). My Goldmine's book doesn't recognize the error, but I still think it is worth something extra.
I have a John Tesh LP, the cover of which is clearly labled: "Contains music"
I remember when I first got into vinyl a trip to New Orleans, to go to Jazz Fest. When away i like to check out local vinyl stores. So i happen on this one down in the quarter, a virtual jazz museum. At the time Coltrane was the shiznit for me, especially late 1965 stuff. So I pick a copy of Live in Seattle. When I get back home to put the record on every things fine untill I go to listen to part 2 of one of the songs and I get Africa Brass from 1961. Another example was my father in law who bought a stck of Christmas CD's at the local pawn shop. So we are sitting there enjoying the sounds of the season when the disc changes and out comes Carols Nakai(native american flute player. The label on the CD was marked Liberace's Christmas.
