text:  Although " T Rex devotees " , in the words of Starr biographer Alan Clayson , claimed that Bolan had ghost @-@ written " Back Off Boogaloo " , Starr later acknowledged that Harrison co @-@ wrote the song by adding some chords and finishing the melody . As on Starr 's 1971 hit single " It Don 't Come Easy " , Harrison was not credited for his songwriting contribution . Starr originally offered " Back Off Boogaloo " to fellow Liverpudlian Cilla Black to record , but she declined , hoping instead to record another new Starr – Harrison composition , " Photograph " .
