George Tyndall Tickner (born September 8, 1946, Syracuse, New York) is an American rock musician who played rhythm guitar and co-wrote songs as a founding member of Journey. Prior to joining Journey, Tickner was a member of the San Francisco psychedelic rock band Frumious Bandersnatch, along with fellow Journey founder Ross Valory. After the release of the band's debut album, he left Journey to attend Stanford Medical School. Upon Tickner's departure, Journey lead guitarist Neal Schon took over all of the band's guitar duties, until Jonathan Cain (keyboards/rhythm guitar) joined in 1981.
Since leaving Journey, Tickner has maintained an active interest in music, as well as contacts with his former bandmates. He and Valory created The Hive, a recording studio where he continued to write and compose music. Tickner, Valory and keyboardist Stevie 'Keys' Roseman came together to form the band VTR, releasing an album called Cinema, which featured other present and former members of Journey, such as Schon, Steve Smith, and Prairie Prince.
In January 2005, Tickner appeared with past and present members of the band to receive a star on the Hollywood Walk of Fame.
