20/05/1975 USA Denver Ebbets' Field
(many sources state 1/5/1975 USA Dallas Broncos Bowl).

This CD appears to be an official release, so nicely the jewelcase is made. It even could be bought in varios official CD stores, the same way as the "Concert Classic CD".
The concert is the same recording as the "Concert Classics", however this time the track titles are correctly stated on the cover.
Varios versions seem to exist. With transparent and with black jewelcases
My version is black and on the back and front of the case a blue sticker is attached. Also a sticker "Limited edition" is attached. Transparent jewelcase therefore seem to have another cover.
When the CD was released in 1998 a Japanese press release is said to staten that the concert was recorded in Dallas Broncos Bowl on 1/5/1975. However latest investigation to a story of a series of recordings from Denver clearly indicate this recording just has to be from a 20/05/1975 gig in Denver. If you think different contact me.
