John Lennon provided backing vocals on Bowie’s “Fame” and co-wrote it.
I did like Lennon and Elton on “Whatever Gets You Through the Night”.
I love contrasting the lyrics with Lennon’s “Whatever Gets You Through the Night” with “Imagine”. Both evil, both near polar opposites.
I never picked out Lennon’s vocals on “Fame”. I found it interesting that Bowie’s first #1 song has gotten little respect compared to “Change”, “Space Oddity”, “Ziggy Stardust” and “Let’s Dance” in the Bowie tributes I’ve seen. His most acclaimed post-Ziggy album, “Scary Monsters”, completely unnoticed except for a stray mention of “Ashes to Ashes”.
If you haven’t heard the most soulless cover song ever, try Peter Noone’s Brit Top 20 version of “Oh! You Pretty Things!” on YouTube. Bowie actually played piano on that disaster.
