Dines was a member of Apostolic Intervention alongside future Humble Pie/Syd Barrett drummer Jerry Shirley. Their song "(Tell Me) Have You Ever Seen Me" was donated by future Humble Pie frontman Steve Marriott.
Later, Dines played in the Keef Hartley Band, fronted by his future T-Rex bandmate Miller Anderson. During Dines' time in the band, they released the albums Halfbreed and The Battle of North West Six. Dines later returned for the album Overdog.
Dines joined T-Rex in mid-1974 and remained until the band disbanded in 1977 due to leader Marc Bolan's death in a car accident.
