No, it's not Austin Powers! Peter and Gordon were a British pop duo, composed of Peter Asher (b. 1944) and Gordon Waller (1945–2009), who achieved international fame in 1964 with their first single, the million-selling transatlantic No.1 smash "A World Without Love". The duo had several subsequent hits in the so-called British Invasion-era.
Peter Asher and his sister Jane were child actors in the 1950's. They played siblings in a 1955 episode of the television series The Adventures of Robin Hood. Jane Asher dated The Beatles' Paul McCartney between 1963 and 1968, and Peter and Gordon recorded several songs written by McCartney but credited to Lennon–McCartney. Those hits included "A World Without Love" (US & UK No.1), "Nobody I Know" (US No.12; UK No.10), "I Don't Want To See You Again" (US No.16, but not a hit in the UK), and "Woman".
Other hits for the duo included "I Go to Pieces", written by Del Shannon and given to Peter and Gordon after the two acts toured together. The duo also recorded remakes of Buddy Holly's "True Love Ways" (US No.14 and UK No.2 in 1965), and The Teddy Bears' "To Know Him Is To Love Him", retitled "To Know You Is To Love You" (US No.24 and UK No.5 in 1965).
Peter and Gordon had their last hit in Britain in late 1966 with "Lady Godiva", which reached No.16 there (and No.6 in the US), whilst their success lasted into 1967 in the US, with "Knight in Rusty Armour" and "Sunday for Tea" both registering in the upper reaches of the Billboard Hot 100 that year.
