I do not like Gladys Knight & the Pips version of "I Heard it Through the Grapevine".
I agree! But have you heard Michael McDonald's version? It's absolutely fantastic. The best version I've ever heard. (not that I am a rabid, crazy fan of his and his gorgeous snowy white hair or anything!
ETA: Oh, how could I forget! Joan Osborne does a version of Heat Wave that is truly wonderful! Much better than previous versions, especially that terrible version by Linda Ronstadt. And I don't even like Joan Osborne, but I have to give credit where it's due. She owns that song!
