Thomas Leslie Gray (9 April 1946 – 21 February 2004) was an English musician best known for his work with glam rock pop band Mud.

[2][3] He was a self-taught musician,[3] and during his school years he played trumpet with a jazz band, and then, with a younger brother, went on to form the skiffle unit The Mourners.

After leaving school he worked for Pearl & Dean, writing commercials, and later for Moss Bros before finding success with Mud.

[4] With a few line-up changes, The Mourners evolved into Mud in February 1966, with Gray on vocals, Dave Mount on drums, Rob Davis on guitar, and Ray Stiles on bass, and won the Search for Sound song contest the same year.

[5][3] After a few unsuccessful singles including "Flower Power", they were signed to Mickie Most's RAK record label, and gained television exposure via an appearance on The Basil Brush Show.
