Holy Crap. I'm wrong. I blew it. Big Time.
I Googled it, and it WAS Deep Purple...side 3 of "Made in Japan". My sign has been wrong for 15 years!!!!
I haven't heard it in a long, long time, and thought it had been edited from my CD version of the Tull album as they removed a few songs from the double LP. Not so. I DID have the Deep Purple Made in Japan double-live album, but never got it on CD.... explaining why I never hear it on any CD I might still listen to.
Wow, I was SO positive!!!
Will an apology, an admission that you ARE indeed wiser, and 20 bucks help you in not mentioning to my wife that I can be SO VERY WRONG ON SOMETHING???
