Dennis Waterman (born 24 February 1948) is an English actor and singer, best known for his tough-guy roles in television series such as The Sweeney, Minder and New Tricks.
He sung vocals on a song called Not Fade Away, which was a left over track from The Explorers sessions.(It now appears on The Complete Explorers album - released in 2001).
As well as starring in Minder, he sang the theme tune, "I Could Be So Good For You", which was a top three UK hit in 1980 and a top 10 hit in Australia, and had a brief singing career. He recorded a song with George Cole "What are we gonna get for 'er indoors". It is sometimes incorrectly believed that he wrote "I Could Be So Good For You", due to the song being credited to 'Waterman/Kenny'. In fact, it was his then wife Patricia Waterman who co-wrote the song with fellow songwriter Gerard Kenny.
