Rock'n'roll forerunner Freddie Bell exerted a profound influence on the young Elvis Presley--not only did Bell's energetic Las Vegas act shape The King's own larger-than-life stage persona, but Presley also lifted his rendition of the raucous Big Mama Thornton classic "Hound Dog" almost note-for-note, notching a landmark single in the process. Born Ferdinando Dominick Bello in Philadelphia on July 29, 1931, Bell studied trombone, bass and drums as a teen, and made his professional debut in support of saxophonist Eddie Ventura--at age 20, he formed his own group, the Bellboys, with pianist Russ Conti, guitarist Frank Brent, trumpeter Jerry Mayo, saxophonist Jack Kane and drummer Chick Keeney, together honing a jump blues-inspired sound heavily indebted to Louis Jordan. After spending six months touring the Midwest, Bell and the Bellboys landed an extended residency at the Las Vegas casino The Sands.
