By the end of 1966 and the beginning of 1967, the group released two more hits, "Gimme Some Lovin'" and "I'm a Man". Both of them sold over one million copies, and were awarded gold record status. These tracks proved to be their two best-known successes, especially in the U.S. (where they had signed to United Artists). Jimmy Miller was their producer. The group starred in "The Ghost Goes Gear" (1966), a British musical comedy film, directed by Hugh Gladwish, and also featuring Sheila White and Nicholas Parsons. The plot involved the group in a stay at the childhood home of their manager, a haunted manor house in the English countryside. The film would later be considered a mistake by Winwood. Steve Winwood left to form Traffic in 1967; his brother, Muff, moved into the music industry working in Artists and repertoire (A&R) at Island Records. In the same period, both the Spencer Davis Group and Traffic featured on the soundtrack of the film "Here We Go Round the Mulberry Bush" released in that year. After the Winwoods' departures, the Spencer Davis Group continued with the addition of guitarist Phil Sawyer (ex-Les Fleur de Lys) and keyboardist/vocalist Eddie Hardin (ex-A Wild Uncertainty). This line-up recorded several tunes for "Here We Go Round The Mulberry Bush" and released the psychedelia sounding, "Time Seller" single in July 1967; the b-side, "Don't Want You No More," also received radio airplay. This was followed by "Mr. Second-Class" in late 1967, which received heavy airplay on Radio Caroline (a pirate radio ship off the British coast), and the album "With Their New Face On" in 1968. At that time Ray Fenwick had replaced Phil Sawyer. The group's last minor hit, "After Tea", was released at the same time by the German band The Rattles, providing competition that led finally to a temporary stop to all activities of the band. The song was originally recorded by the Dutch group After Tea, which included guitarist/singer Fenwick amongst its members. After one further single ("Short Change"), at that time Eddie Hardin and Pete York had left to form the duo Hardin & York. They were replaced by future Elton John band member Dee Murray on bass and Dave Hynes on drums. Nigel Olsson replaced Hynes, and this lineup produced the album "Funky" in 1969 (only released in the USA on Date Records, a subsidiary of CBS) before splintering.
