"Sunshine" was not originally planned for release, but when an engineer accidentally erased the master of a track called "Please Find Me" near the end of sessions for the album, "Sunshine" was used to fill the hole.
The song was released as a single and first gained popularityon Boston radio, then nationwide, hitting #4 on the Billboard Hot 100 chart on January 15, 1972 and earning a gold record. Here's Edwards' take on its success: "It was just at the time of the Vietnam War and Nixon. It was looking bad out there. That song meant a lot to a lot of people during that time--especially me."
In July 2007, the original Jonathan Edwards recording joined the list of 1960s protest songs used to sell high-end consumer products when it was used as the only audio in a Jeep television spot, part of the Heritage campaign developed by the Cutwater agency.
