Terence William "Blondie" Chaplin (born 7 July 1951) is a musician from Durban, South Africa who first became known to international audiences through his time in the early 1970s as a singer and guitarist for The Beach Boys. Chaplin was also listed as a co-producer, sang lead vocals with fellow South African musician Ricky Fataar (drummer) and composed, with Fataar, "Here She Comes" and "Hold on Dear Brother" on the twenty-third official Beach Boys album, Carl and the Passions – "So Tough", released in 1972. He is known as a long-term backing vocalist, percussionist, and acoustic rhythm guitarist for the Rolling Stones on their recordings and tours over a 15-year period, starting in 1997.
Blondie Chaplin, along with drummer Ricky Fataar, joined the Beach Boys when original drummer Dennis Wilson suffered a hand injury that left him unable to play the drums for almost two years. For the Beach Boys, it was a period in which long-time member Bruce Johnston had departed the band, and one-time leader Brian Wilson's participation in the group was very limited. As a result, Chaplin and Fataar joined the Beach Boys as full-fledged members and not merely as backing musicians. Chaplin left the group in 1973 after a dispute with the Beach Boys' management; Fataar remained with the band until the following year.
