Ph.D. (band)

Ph.D. were a British duo best known for their UK top 10 hit "I Won't Let You Down" in April 1982, which had been a hit the previous year throughout Europe.

The band was a duo, but it took its name from the initial letters of the surnames of the three performers on the group's original recordings: Phillips, Hymas and Diamond. Though drummer Simon Phillips appears on a number of the band's tracks as a session player, he was not an official member of Ph.D., which consisted of keyboard player Tony Hymas and vocalist Jim Diamond.
