Greg Leon... First guitarist for Dokken and Randy Rhoads replacement in Quiet Riot!!!! Also wrote the riff that became Ozzy Osbourne's "Crazy Train"

Greg Leon is a Los Angeles hard rock guitarist notable for his stints in Quiet Riot and Dokken. He was also in a pre-Mötley Crüe band with Tommy Lee called Suite 19.  Leon is considered an influential and important musical personality in the Hollywood hard rock/heavy metal scene of the late 70s and early 80s, playing an integral part in the successive fortunes of the acts he was associated with.  Greg later fronted the Greg Leon Invasion, with bassist Joey Vera(later of Armored Saint, Fate's Warning and Anthrax) and drummer Carl Elizondo (later of Jag Wire, and playing under the stage name Carl James). Elizondo and Vera's replacement, Chuck Stevens, played with Leon on the Greg Leon Invasion picture disc released by Azra/R2R in 1983. He took the place of Randy Rhoads in Quiet Riot, and as the pre-George Lynch guitarist in Dokken.  During this period Leon also had a considerable local reputation as a guitar teacher, working at Randy Rhoads' mother's guitar studio in Burbank. Leon had several incarnations of the Invasion and played with various LA acts after his exciting early days. Leon also had a brief time with Greenworld Records' Midwestern act Vyper, while at the same time gathering a name for himself as a guitar amp modifying specialist.  In the late 90s, Leon fronted a band called Wishing Well which also featured Survivor drummer Marc Droubay and English-born bassist Stuart Brooks (ex-Black Cat Bones, Leafhound). 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, taking the group for a European festival tour in 2005 on the strength of new recordings, coupled with the myth related to his name.
