"I Surrender" is of "Difficult to Cure" the fifth studio album by the British hard rock band, Rainbow, and was released in 1981. The album marked the further commercialization of the band's sound, with Blackmore once describing at the time his like of the rock band, Foreigner. The album material was started with singer Graham Bonnet still in the band, getting as far as recording an early version of "I Surrender", before Bonnet left the band due to his dissatisfaction over the material. American singer Joe Lynn Turner, formerly of Fandango was recruited and sang over already completed musical tracks. Turner stated that, because of this, he was singing in higher keys than he would do normally (and would do subsequently). "I Surrender" would be the band's highest charting single in the UK, reaching No. 3.
