He chose his stage name while launching his career. It is an amalgamation of his childhood nickname, Hank, which he used to differentiate himself from friends also named Brian, and the first name of Marvin Rainwater, the country and rockabilly singer.

Sixteen-year-old Marvin and his Rutherford Grammar School friend, Bruce Welch, met Johnny Foster, Cliff Richard’s manager, at The 2i’s Coffee Bar in Soho, London. Foster was looking for a guitarist for Cliff Richard’s UK tour and was considering Tony Sheridan. Instead, he offered Marvin the position. Marvin joined the Drifters, as Cliff Richard’s group was then known, provided there was a place for Welch.

Marvin met Richard for the first time at a nearby Soho tailor’s shop, where Richard was having a fitting for a pink stage jacket. The Drifters had their first rehearsal with Richard at the Webb family home (Cliff’s parents) in Cheshunt, Hertfordshire.

In 1988, Marvin collaborated with French keyboardist and composer Jean Michel Jarre on the track “London Kid”, on Jarre’s Revolutions album and was a guest in Jarre’s Destination Docklands concert at London’s Royal Victoria Dock. Jarre said the Shadows’ success had influenced him and led to his decision to devote his career to instrumental music.
