Frampton was replaced by Clem Clempson and Humble Pie moved towards a harder sound emphasising Marriott's blues and soul roots.
Their first record with Clempson, Smokin', was released in 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 in one double album, as 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 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.
Thunderbox was released in 1974, and Street Rats a year later.
In 1975, Humble Pie conducted their Goodbye Pie Tour before disbanding.
