At the age of 14 his childhood friend Bob McKeag (aka Bubs McKeg) invited him to join his popular band The Igniters as lead singer.
As Jimmy Mack and the Music Factory, they recorded a Top 40 single, Baby, I Love You, b/w The Hunter Gets Captured by the Game - both featuring Frank on lead vocals.
In 1970 Frank began a four-year stint as vocalist and keyboard player with The Jaggerz, the Pittsburgh band that had scored a Top Ten hit with The Rapper in 1969.
Working with producer/manager Dave Shaffer and producer Tom Cossie, the band signed a contract with the Atlantic subsidiary Big Tree Records, and released a Top 40 hit cover of Marvin Gaye's Ain't That Peculiar in December 1974.
Frank's gigs with the band took him to venues far and wide - from arenas with acts like Kiss and Aerosmith, to the "upstairs room" of New York's infamous Warhol hangout, Max's Kansas City.
On February 15, 1975, he appeared with Diamond Reo performing "Ain't That Peculiar" and "Movin' On" on Dick Clark's American Bandstand, season 18, episode 19.
Soon, he was talking with Warren King about forming a new band to be called The Silencers, and together they recruited Dennis Takos on keyboards, Mike Pella on bass, and Ron "Byrd" Foster on drums.
That year they performed the first of four sold-out reunion shows that drew a total of 3,000 loyal fans from all over the U.S. Reinvigorated, they reunited on a permanent basis in 2010, and have been playing at festivals, clubs and casinos all over the tri-state region.
