Ph.D is spelt as such on album tracklistings so this is official. Ph.D. is a British group that managed a UK Top 10 hit with "I Won't Let You Down" in April 1982, although the song had been a hit the previous year throughout Europe. The band took its name from the initial letters of its three members' surnames; Phillips, Hymas and Diamond. Singer Jim Diamond formed the group with former Jeff Beck Group members Tony Hymas and Simon Phillips in the early 1980s. Read more about Ph.D on Last.fm.
