Clint Warwick, born Albert Eccles was born in Aston, Birmingham, England (25 June 1940 – 15 May 2004), was the original bassist for the rock band The Moody Blues.

The Moody Blues released one album with Warwick on bass, Go Now - The Moody Blues #1 (USA release on London Records) also released as The Magnificent Moodies on Decca in the UK, with sleeve notes by Donovan. The album yielded the hit single "Go Now", which reached No. 1 in the UK in January 1965, and the Top Ten in the U.S. Warwick took one co-lead vocal on that album with Denny Laine on the track "I've Got A Dream" (which featured Ray Thomas on flute). The closing track "'Bye Bye Bird" was issued as an overseas single and became a hit in France.
Warwick was also on the EP The Moody Blues issued on Decca in 1964, and appeared on all their Decca singles, beginning with their debut, "Steal Your Heart Away" (1964), then "Go Now", "I Don't Want to Go On Without You", "Everyday", "From The Bottom Of My Heart (I Love You)" (all 1965), plus "Boulevard De La Madeline" (1966) up to "Life's Not Life" in 1966.
Warwick's and Denny Laine's era with The Moody Blues was featured on various compilation albums on both vinyl and CD, such as The Moody Blues Collection. A later CD issue of The Magnificent Moodies in 2006 included the rare track "People Gotta Give" (mistitled as "People Gotta Go") - a Mike Pinder - Denny Laine composition from the Boulevard De La Madeline French EP release.
Film footage survives of the original era of The Moody Blues performing "Go Now" on BBC TV's The Beat Room (later included in the BBC's Sounds of The Sixties) plus the first single's B-side "Lose Your Money (But Don't Lose Your Mind)" on Ready Steady Go! in August 1964 with Warwick and Denny Laine in the line-up, and has been re-screened in recent years.
Feeling stressed by touring, Warwick left the band and his music career in 1966 to become a carpenter and spend time with his family. He was replaced briefly by Rod Clark and then by John Lodge.

He died in Birmingham on 15 May 2004 at the age of 63.
