Flying Mother Nature's Silver Seed To A New Home In the Sun

Neil Young never cracked the Top 40 with his classic tune "After The Gold Rush", but the acapella version by Prelude made it to #22 in 1974. Checking I-Tunes, I found several cover versions by "name" artists, including Dolly Parton, Linda Ronstadt, Emmylou Harris, KD Lang and Natilie Merchant.... hmmmm, all women, what can it mean?
