"California Soul" is a pop-soul tune written by Ashford & Simpson, issued originally as the B-side of The Messengers' single, "Window Shopping" in 1967 under the Motown group of labels. It was then issued as a single by American pop quintet The 5th Dimension in late 1968, and also covered by Motown vocal duo Marvin Gaye and Tammi Terrell, and Marlena Shaw the next year. It was Marvin's and Tammi's last single together when released in early 1970. The song is also featured in The Italian Job (2003). An exclusive remixed version featuring Ya Boy was used in The Lincoln Lawyer (2011).
