was certified gold by the RIAA. "I Don't Need No Doctor" became an FM radio standard in the US, peaking at No. 73 on the Billboard Hot 100 and propelling the album up the charts. By the time of the album's release, Frampton had left the band and went on to enjoy success as a solo artist. 1972–1975: Clem Clempson, The Blackberries and further success Frampton was replaced by Clem Clempson and Humble Pie moved toward a harder sound emphasising Marriott's blues and soul roots. Their first record with Clempson, Smokin', was released in March 1972, along with two singles "Hot 'n' Nasty" and "30 Days in the Hole" (the latter of which became one of their best-known efforts). It was the band's most commercially successful record and reached No. 6 on the US charts, helped by a busy touring schedule. After the success of Smokin, the band's record label A&M released Humble Pie's first two Immediate albums as one double album titled Lost and Found. The marketing ploy was a success and the album charted at No. 37 on the Billboard 200. Looking for a more authentic R&B sound, Marriott hired three female backing vocalists, The Blackberries. The trio consisted of Venetta Fields, Clydie King and Sherlie Matthews, who was later replaced by Billie Barnum. They had performed with Ike and Tina Turner as The Ikettes and with Ray Charles as The Raelettes. This new line-up included Sidney George on saxophone for the recording of Eat It, a double album released in April 1973 made up of Marriott originals (some acoustic), R&B numbers, and a Humble Pie concert recorded in Glasgow. The album peaked at No. 13 in the US charts. Album number seven, Thunderbox, was released in February 1974 and Street Rats a year later. Street Rats (February 1975) was created at the same time as Marriott was producing a solo album and a collaboration album with Greg Ridley. After the release of this album and their 1975 "Goodbye Pie Tour", Humble Pie disbanded, citing musical differences. Marriott went on to produce his first solo album Marriott and promptly moved back to the UK. 1979–1981: Steve Marriott's Humble Pie without Frampton and Ridley In late 1979, Marriott and Shirley, now managed by Leber-Krebs, revived Humble Pie, adding Bobby Tench, former vocalist and guitarist from The Jeff Beck Group, along with bassist Anthony "Sooty" Jones from New York.
