ska became the music of choice for young Jamaicans seeking music that was their own. Ska also became popular among mods in Britain. In the mid-1960s, ska gave rise to rocksteady, a genre slower than ska featuring more romantic lyrics and less prominent horns. Theories abound as to why Jamaican musicians slowed the ska tempo to create rocksteady; one is that the singer Hopeton Lewis was unable to sing his hit song "Take It Easy" at a ska tempo. The name "rocksteady" was codified after the release of a single by Alton Ellis. Many rocksteady rhythms later were used as the basis of reggae recordings, whose slower tempos allowed for the "double skank" guitar strokes on the offbeat. Emergence in Jamaica Reggae developed from ska and rocksteady in the late 1960s. Larry And Alvin's "Nanny Goat" and the Beltones' "No More Heartaches" were among the songs in the genre. The beat was distinctive from rocksteady in that it dropped any of the pretensions to the smooth, soulful sound that characterized slick American R&B, and instead was closer in kinship to US southern funk, being heavily dependent on the rhythm section to drive it along. Reggae's great advantage was its almost limitless flexibility: from the early, jerky sound of Lee Perry's "People Funny Boy", to the uptown sounds of Third World's "Now That We’ve Found Love", it was an enormous leap through the years and styles, yet both are instantly recognizable as reggae. The shift from rocksteady to reggae was illustrated by the organ shuffle pioneered by Jamaican musicians like Jackie Mittoo and Winston Wright and featured in transitional singles "Say What You're Saying" (1968) by Eric "Monty" Morris and "People Funny Boy" (1968) by Lee "Scratch" Perry. Early 1968 was when the first bona fide reggae records were released: "Nanny Goat" by Larry Marshall and "No More Heartaches" by the Beltones. That same year, the newest Jamaican sound began to spawn big-name imitators in other countries. American artist Johnny Nash's 1968 hit "Hold Me Tight" has been credited with first putting reggae in the American listener charts. Around the same time, reggae influences were starting to surface in rock and pop music, one example being 1968's "Ob-La-Di, Ob-La-Da" by the Beatles. The Wailers, a band started by Bob Marley, Peter Tosh and Bunny Wailer in 1963, is perhaps the most recognized band that made the transition through all three stages
