Roots of The 5th Dimension

The Mamas & the Papas were an American-Canadian folk rock vocal group that recorded and performed from 1965 to 1968, with a brief reunion in 1971. The group was a defining force in the music scene of the counterculture of the 1960s. Formed in New York City, the group consisted of Americans John Phillips, Cass Elliot, and Michelle Phillips, and Canadian Denny Doherty. Its sound was based on vocal harmonies arranged by John Phillips – the songwriter and leader of the group – who adapted folk to the new beat style of the early 1960s.

Johnny Rivers is an American retired musician. He achieved commercial success and popularity throughout the 1960s and 1970s as a singer and guitarist, characterized as a versatile and influential artist. Rivers is best known for his 1960s output, having popularized the mid-1960s discotheque scene through his live rock and roll recordings at the Los Angeles nightclub Whisky a Go Go, and later shifting to a more orchestral, soul-oriented sound during the latter half of the decade. These developments were reflected by his most notable string of hit singles between 1964 and 1968, many of them covers. They include "Memphis", "Mountain of Love", "The Seventh Son", "Secret Agent Man", "Poor Side of Town", "Baby I Need Your Lovin'", and "Summer Rain". Rivers had a total of nine top-ten hits and 17 top-forty hits on the US charts from 1964 to 1977.
