 Lead singer Gladys Knight recalled on A&E's "Biography" that she and the group were regarded as a second-string act and that "Diana (Ross) & The Supremes, The Temptations and Marvin Gaye were given all the hits, while we took the leftovers".While on Motown, Knight & The Pips recorded for Soul Records, a label Motown used for acts that recorded material with more of an R&B flavor than a pop flavor.In 1972, the group had success with their cover of musician Kris Kristofferson's ballad, "Help Me Make It Through the Night".
