Christopher McGregor (24 December 1936 – 26 May 1990), was a South African jazz pianist, bandleader and composer born in Somerset West, South Africa.

McGregor grew up in the then Transkei (now part of the Eastern Cape Province) where his father was headmaster at a Church of Scotland mission institution called Blythswood. Here he was exposed to the music of the local amaXhosa people.

This music is a rich and varied music which pervaded every aspect of life - from formal rituals to the casual activities and encounters of everyday life, like herding cattle or just walking home in the evening. Music was everywhere. And this music, as explained in Dave Dargie's seminal book Xhosa Music, is complex. Dargie mentions the following as examples of this complexity which might be seen to have influenced McGregor in his own music, both as composer/arranger and as band leader: "... a great number of style characteristics are to be found: relating not only to harmony and scale, but to melody, structure and phrasing, form, rhythm, instrumentation, singing techniques, and so on."

Lee Dorsey (December 24, 1924 – December 2, 1986) was an African American pop/R&B singer during the 1960s. Much of his work was produced by Allen Toussaint with instrumental backing provided by the Meters.

Born Irving Lee Dorsey in New Orleans, Louisiana, Dorsey moved to Portland, Oregon when he was ten years old. He served in the United States Navy and began a career in prizefighting. Boxing as a light heavyweight in Portland in the early 1950s, he fought under the name "Kid Chocolate" and was quite successful.

Dorsey met songwriter/producer Allen Toussaint at a party in the early 1960s, and was signed to the Fury record label. The song that launched his career was inspired by a group of children chanting nursery rhymes - "Ya Ya" went to number seven on the Billboard Hot 100 in 1961. It sold over one million copies, and was awarded a gold disc. He recorded other songs for Fury before the label folded, and Dorsey went back to his car repair business.

Toussaint later came back on the Amy label and began to work with Dorsey once again. From 1965 to 1969 Dorsey put seven songs in the Hot 100, the most successful of which was "Working in the Coal Mine" in 1966. It was to be his second and last Top Ten song. In 1970 Dorsey and Toussaint collaborated on an album entitled Yes We Can; the title song was Dorsey's last entry in the singles chart. It was later a hit for the Pointer Sisters under the title, "Yes We Can Can".

Ernie Andrews (born December 25, 1927, Philadelphia, Pennsylvania) is an American jazz, blues, and pop singer. He grew up in Los Angeles, California, and one of his first jobs was with the Harry James orchestra. He went on to be recorded by Columbia Records and others. His career declined in the 1960s and 1970s, but would rebound in the 1980s.

He latterly recorded with the Capp/Pierce Juggernaut Band, Gene Harris, Jay McShann, and the Harper Brothers. Andrews played a leading part in the documentary film, Blues for Central Avenue.

Cactus is an American hard rock supergroup, formed in 1970.

Cactus was initially conceived as early as late 1969 and originally featured the Vanilla Fudge rhythm section of bassist Tim Bogert and drummer Carmine Appice, guitarist Jeff Beck, xylophone player/vocalist Adele Smitchell, and Rod Stewart (also from the already dissolved Jeff Beck Group). However, Beck had an automobile accident and was out of the music scene for over a year and Stewart joined Ronnie Wood in Faces.

Early 1970 Appice and Bogert brought in blues guitarist Jim McCarty from Mitch Ryder's Detroit Wheels and The Buddy Miles Express, and singer Rusty Day (born Russell Edward Davidson) from Amboy Dukes.

This line-up managed three albums (Cactus, One Way...Or Another and Restrictions) before intraband troubles led to McCarty quitting at the end of 1971. Shortly afterwards Day was fired from the group. The fourth and last Cactus album ('Ot 'N' Sweaty) featured original rhythm section Bogert and Appice joined by Werner Fritzschings on guitar, Duane Hitchings on keyboards and Peter French (ex-Leaf Hound and Atomic Rooster) on vocals.
