Ranked #8 in TV Guide's list of "TV's 25 Greatest Teen Idols" (23 January 2005 issue).
The one time protégé of actor Sal Mineo, Mineo produced two early songs for Bobby -- "Nobody's Sweetheart" and "I Wanna Hear It from Her". Moreover, Mineo was instrumental in Bobby landing a regular job as a "house singer" on the popular teen variety show Shindig! (1964).
Sal Mineo bought Sherman a set of drums when he helped him break into the music industry in 1963-1964. (Mineo had learned to play the drums for his role of Gene Krupa in The Gene Krupa Story (1959).) In 1970, when Mineo was broke and Sherman was riding high after appearing in the TV series Here Come the Brides (1968) and scoring big as a pop star, Mineo's lover Courtney Burr contacted Sherman and requested that he reimburse his former mentor for the drums. Sherman's manager sent Mineo $3,000 (approximately $18,000 in 2014 dollars, when adjusted for inflation).
A qualified EMT, Sherman joined the LAPD in 1988 as a specialist officer, training police recruits in first aid and CPR.
In 1999, Sherman joined the San Bernardino County Sheriff's Department in the same capacity he held with the LAPD.
