We'll Fly You to the Promised Land by Les Humphries Singers (1971)
The Les Humphries Singers were sort of your standard Jesus Music group of the early 70's - every song sounded like "Age of Aquarius (Let the Sunshine In)" with a gospel twist. The album contains your predictable mix of (1) hippie Christian tunes like "Jesus Cried on the Day He Died", (2) hippie social message songs like "Melting Pot", and (3) hippie rock covers like "Hey Joe".
The group consisted of diverse ethnic origins and nationalities. Their biggest hit came a German cover version of The Bellamy Brothers' hit "Let Your Love Flow", translated to "Ein Bett im Kornfeld". Here's one song off the We'll Fly You to the Promised Land album titled "Bucket of Sweat".
By the mid-1970's, Les Humphries Singers had all but abandoned any Christian pretense. They released rock, jazz and even disco albums.
What I find particularly interesting about this group is their main vocalist, John Lawton. His funky mug is front and center on the front and/or back of every record.
