“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. The track was further popularised by Joe Cocker when he named his 1987 album after the song. His version of the song was re-released in 1992 and reached number 17 in the UK. In Australia, the Howard government used the Joe Cocker version to promote the television advertisements for the introduction of the Goods and Services Tax (GST) in 2000. (Wikipedia)
