Hotlegs (very briefly Doctor Father) was a short-lived English band best known for their hit single "Neanderthal Man" in 1970.

The band consisted of Eric Stewart, Kevin Godley, Lol Creme and – briefly – Graham Gouldman.

The Mindbenders disbanded in November 1968[1] and Stewart teamed with Peter Tattersall, a former road manager for Billy J. Kramer and the Dakotas, and Gouldman, a fellow Mindbender and successful songwriter, to become joint owners of a Stockport recording studio which in 1969 was renamed Strawberry Studios.

Stewart and Gouldman enlisted Godley and Creme, longtime friends of Gouldman who had earlier launched an abortive career under entrepreneur Giorgio Gomelsky as duo Frabjoy and Runcible Spoon, and the team gained work writing and performing bubblegum songs under a variety of band names for US producers writer-producers Jerry Kasenetz and Jeffry Katz of Super K Productions, as well as other session work.

"Neanderthal Man" was created by the trio of Stewart, Godley and Creme as they dabbled with newly installed recording equipment at Strawberry Studios, perfecting drum layering on a four-track machine.

The song consisted primarily of a chanted chorus backed by Stewart's and Creme's acoustic guitars and a lumbering drum rhythm provided by Godley.

Released on Pye, it was an expanded reworking of "There Ain't No Umbopo", a song the trio had recorded in 1969 under the guise of American bubblegum pop group Crazy Elephant.

[3] Despite regular airplay on Radio Northsea, "Umbopo" did not appear on the British charts and was the sole release by Doctor Father.

The decision to create a new band name for the release of "Umbopo" was consistent with the trio's operating procedure of the previous year: working with Kasenetz, Katz and Manchester songwriter Graham Gouldman, they had recorded a large number of songs under names including Silver Fleet, Fighter Squadron and Festival.

Gouldman, newly returned to the UK, joined the band on bass, marking the gigs as the first at which the four future members of 10cc played live on stage.

"[3] The group was put with comedian John Paul Joans in order to record a single aimed at the Christmas market, and the result – "The Man From Nazareth" – was a top 30 hit.

We should have stayed in England, gone on tour, made promotional appearances, given interviews to the Press and TV and so on, but we just vanished to Antigua.

"[3]After Thinks: School Stinks received worldwide release, it was repackaged (in the UK) by the Philips label in December 1971 as Song, with several tracks replacing originals, including "Neanderthal Man".
