From 1968 to 1973, Badfinger recorded five albums for Apple Records and toured extensively before they became embroiled in the chaos of Apple's dissolution. They are recognised for their influence on the 1970s power pop genre and are estimated to have sold 14 million records.

The Walker Brothers were an American pop group formed in Los Angeles in 1964 by John Walker and Scott Walker, with Gary Walker joining shortly after.

Between them was the UK No. 3 hit "My Ship is Coming In". They provided a unique counterpoint to the British Invasion by achieving far more success in the UK than in their home country.
