SOS: how to get the *TRUE* "River Deep, Mountain High"?

Does anybody know what's going on with "River Deep, Mountain High"? This is one of my top favorite songs and I can't find it anymore on any record by Ike & Tina Turner. I want the version produced by Phil Spector. Where can I find it? Thanks, Patrice (worried to buy another Ike & Tina compilation).
