Uncle Neil is a cool singer/songwriter. I don't idolize the ground he walks on like some people, but I am certainly a fan. Here's a list of some of my favorite Neil Young songs that other artists sang lead vocals on.
Flying On The Ground Is Wrong (Sung by Richie Furay for Buffalo Springfield)
Nowadays Clancy Can't Even Sing (Sung by Richie Furay and Stephen Stills for Buffalo Springfield)
Lotta Love (sung by Nicolette Larsen [and also by Neil Young])
On The Way Home (Sung by Richie Furay for Buffalo Springfield and Poco)
Bonus Song: Only Love Can Break Your Heart (Sung by Neil Young AND Crosby, Stills, Nash and Young)
