Who wrote the song 'It Don't Come Easy'?   The released song is credited to Starkey, Richard (Ringo Starr). But years later Ringo stated that he wrote the song with George Harrison. Some say Harrison wrote the â¦song and gave it to Ringo, as it has a feeling and style that seems George's. But Ringo certainly was a talent in his own right.   The lead vocals are Ringo's, and the backing tracks are by Badfinger's Pete Ham and Tom Evans.
