In 1968, Hans Bouwens (born 8 December 1944) from Wormerveer joined the band "Soul Invention", a soul band that had been founded the previous year by Henk Kramer in Assendelft and played covers of songs by Otis Redding and Sam and Dave.

The band consisted of Job Netten (guitar), Henk Kramer and Eric Bardoen (saxophone), Jacques Greuter (born 18 August 1942 – died 17 March 2018, keyboard and flute), Theo Vermast and later Jan Visser (bass), and Ton Vredenburg (drums).

In 1974, singer Lida Bond (born 30 July 1952) joined the Selection, and combining her voice with Baker's proved highly successful.

The band experienced a brief return to the international charts in 1992 when the song "Little Green Bag" was used in the title sequence of the film Reservoir Dogs and in Machos, a Chilean soap opera in 2003.
