In the late 1990s, Leon fronted a band called Wishing Well which also featured Survivor drummer Marc Droubay and English-born bassist Stuart Brooks (ex-Black Cat Bones, Leaf Hound, The Pretty Things). The trio released their eponymous debut album in 1997. However, by 2003 Leon was once again playing the LA club scene under the name The Greg Leon Invasion, featuring Boston-born bassist George Roelke and Ohio-born drummer Greg Stevens, taking the group for a European festival tour in 2005 on the strength of new recordings, coupled with the myth related to his name. The line-up also performed July 13, 2007 at the annual 1980s-era hard rock music festival Rocklahoma. In 2008 former White Lion drummer Greg D'Angelo replaced Stevens in the band.
