Peter & Gordon were a British Invasion-era performing duo, formed by Peter Asher and Gordon Waller, that rocketed to fame in 1964 with "A World Without Love". Peter Asher's sister (the actress Jane Asher) was dating Paul McCartney (of The Beatles), and so Peter & Gordon recorded several songs written by McCartney, with or without John Lennon. "I Go To Pieces" was written by Del Shannon and given to the duo after the two acts toured together
