Who are the members in the band Pure Prairie League?

the original lead singer was Craig Fuller, who sang lead on "Amie" in 1975.

he was replaced by Vince Gill in 1979. (That's THE Vince Gill of Country Music fame)

New answer 6/2011- Actually, it was Larry Goshorn who was the lead singer of Pure Prairie League after Craig left and sang Amie on the road for a few years. Also, Larry Goshorn was replaced by Vince Gill. Vince did not replace Craig Fuller, who was no longer with the group!
