During these years, many artists and their labels know that having Paul Butterfield: Harmonica printed on the album cover will not only help record sales, but also add a level of distinction to individual songs. It is a combination of the full visceral tone he pulls out of his harmonica, and extraordinary timing that develops his profile as the most recognizable harmonica player in mainstream popular music. His only potential rival being Nashville's studio king, Charlie McCoy, he mostly works with country and country crossover artists.
During his reign as the most sought-after harmonica sideman in Rock, Butterfield plays a supporting role on records by many artists who record everything from Traditional Folk, Blues, Jazz/Rock Fusion, and even mainstream pop. In fact, next to Charlie McCoy, Paul Butterfield's harmonica is a noticeable part of more pop records than anyone during the later half of the twentieth century.

In 1969, Hardin releases the album Suite for Susan Moore and Damion. The last track of side one is Little Sweet Moments which features Butterfield's funky harmonica in a supporting role.
