From the excellent movie/documentary, "Standing in the Shadows of Motown". The Funk Brothers, the session musicians featured in this documentary, has played in more #1 hits than the The Beatles, Elvis Presley, The Rolling Stones, and The Beach Boys combined. http://en.wikipedia.org/wiki/The_Funk...

Later in the video, "Ain't Too Proud to Beg" Funk Brothers and Ben Harper
