of early Jamaican popular music: ska, rocksteady and reggae. Over a dozen Wailers songs are based on or use a line from Jamaican mento songs. Other significant ska artists who made the leap to reggae include Prince Buster, Desmond Dekker, Ken Boothe, and Millie Small, best known for her 1964 blue-beat/ska cover version of "My Boy Lollipop" which was a smash hit internationally. Notable Jamaican producers influential in the development of ska into rocksteady and reggae include: Coxsone Dodd, Lee "Scratch" Perry, Leslie Kong, Duke Reid, Joe Gibbs and King Tubby. Chris Blackwell, who founded Island Records in Jamaica in 1960, relocated to England in 1962, where he continued to promote Jamaican music. He formed a partnership with Lee Gopthal's Trojan Records in 1968, which released reggae in the UK until bought by Saga records in 1974. International popularity Reggae's influence bubbled to the top of the U.S. Billboard Hot 100 charts in late 1972. First Three Dog Night hit No. 1 in September with a cover of the Maytones' version of "Black and White". Then Johnny Nash was at No. 1 for four weeks in November with "I Can See Clearly Now". Paul Simon's single "Mother And Child Reunion" – a track which he recorded in Kingston, Jamaica with Jimmy Cliff's backing group – was ranked by Billboard as the No. 57 song of 1972. In 1973, the film The Harder They Come starring Jimmy Cliff was released and introduced Jamaican music to cinema audiences outside Jamaica. Though the film achieved cult status its limited appeal meant that it had a smaller impact than Eric Clapton's 1974 cover of Bob Marley's "I Shot the Sheriff" which made it onto the playlists of mainstream rock and pop radio stations worldwide. Clapton's "I Shot the Sheriff" used modern rock production and recording techniques and faithfully retained most of the original reggae elements; it was a breakthrough pastiche devoid of any parody and played an important part in bringing the music of Bob Marley to a wider rock audience. By the mid-1970s, authentic reggae dub plates and specials were getting some exposure in the UK on John Peel's radio show, who promoted the genre for the rest of his career. Around the same time, British filmmaker Jeremy Marre documented the Jamaican music scene in Roots Rock Reggae, capturing the heyday of Roots reggae.
