"Unchain My Heart" is a song written by Bobby Sharp and recorded first in 1961 by Ray Charles and in 1963 by Trini Lopez and later by many others. Sharp, a drug addict at the time, sold the song to Teddy Powell for $50. Powell demanded half the songwriting credit. Sharp later successfully fought for the rights to his song. In 1987, he was also able to renew the copyright for his publishing company, B. Sharp Music.

Trinidad López III was an American singer, guitarist, and actor. His first album included a cover version of Pete Seeger's "If I Had a Hammer", which earned a Golden Disc for him. His other hits included "Lemon Tree", "I'm Comin' Home, Cindy" and "Sally Was a Good Old Girl". He designed two guitars for the Gibson Guitar Corporation, which are now collectors’ items. A documentary on his life and career, "My Name is Lopez" was released in April 2022.
