He toured with Buddy Rich in the late 1960s, occupying one of the alto saxophone chairs, and visited Africa on a U.S. State Department tour with Oliver Nelson's group.
Watts played alto saxophone with The Tonight Show Band under Doc Severinsen for 20 years. He was a featured soloist on many of Marvin Gaye's albums on Motown during the 1970s, as well as on many other pop and R&B sessions during his 25 years as a studio musician in Los Angeles. He has won two Grammy Awards as an instrumentalist.
Watts was added to the lineup of backing musicians on the fifth show of the Rolling Stones American Tour 1981 and was with them until the end of that tour. Throughout the tour, Watts's influence on the Stones' live performance grew significantly, with the Stones jamming longer and longer over tracks such as "Just My Imagination" and Let Me Go". Watts can be heard on Still Life, the live album recorded during the tour.
In the mid 1980s, Watts decided to rededicate himself to jazz. He recorded and toured with German guitarist and composer Torsten de Winkel, drummer Steve Smith, and keyboardist Tom Coster. He was invited to join Charlie Haden's Quartet West; the two met backstage one night after Haden heard Watts play "Nightbird" by Michel Colombier.
Watts also played on soundtracks for the movies Grease and The Color Purple and on the theme song for the TV show Night Court.[1] In 1982, his version of "Chariots of Fire" was featured in the Season 4 episode of WKRP in Cincinnati ("The Creation of Venus"). He was featured on one of Windows XP's sample tracks, "Highway Blues" by New Stories.[2]
In 1986, Watts visited South America with the Pat Metheny Special Quartet alongside Charlie Haden and Paul Wertico, playing at Shams in Buenos Aires, Argentina.
In 2008, his album Analog Man won the Independent Music Award for Best Jazz Album.[3] He played on Kurt Elling's album Dedicated to You, which won the Grammy Award for Best Jazz Vocal Album in 2011.
