Sunshine Superman is the third studio album by British singer-songwriter Donovan. It was released in the United States on August 26, 1966, but was not released in the UK because of a contractual dispute. In June 1967, a compilation of tracks from this album and the follow-up Mellow Yellow was released as Sunshine Superman in the UK. Both versions were named after Donovan's hit single released in the US in July 1966. The album was Donovan's most successful, peaking at number 11 in the US and remaining on the Billboard Top LPs chart for six months. The UK edition peaked at number 25. The tracks from Sunshine Superman and Mellow Yellow were not mixed into stereo, with the exception of "Season of the Witch", until the 2011 2-CD deluxe edition issued by UK EMI. History Whilst still incorporating folk music, these recordings mark a distinct change in Donovan's music, representing some of the first psychedelia released. A full rock band backs up Donovan on many of the songs, and the instrumentation had been expanded, being one of the first pop albums extensively to use the sitar and other unique musical instruments. This change is partially the result of working with producer Mickie Most, whose pop sensibilities led to chart hits for many other artists at the time. Sunshine Superman involves psychedelic rock, psychedelic folk, psychedelic pop and folk rock styles. The album's lyrical content encompasses Donovan's increasing ability to portray "Swinging London" and give listeners an insider's look into the mid-sixties pop scene. He was close to the Beatles and Brian Jones at this time, and he became widely known after "Sunshine Superman" became a chart-topper in the US, and hit number 2 in the UK. Donovan's penchant for name-dropping in songs such as two influenced by his travel to Los Angeles, "The Trip" and "The Fat Angel" (written for Cass Elliot) coupled with his chart success helped elevate him to superstar status. In addition to noting the people in the pop scene, Donovan recorded "Bert's Blues" for his friend and folk music notable Bert Jansch. Contrasting this modern bent was Donovan's fascination with medieval themes in such songs. The title track was also inspired by Brian Jones' girlfriend Linda Lawrence. Several other songs were recorded for Sunshine Superman, but did not make the cut. These include "Museum" (later rerecorded and released on Mellow Yellow), "Superlungs My Supergirl" (later rerecorded
