The second episode of "The Singer and the Song" is devoted to the curious history of "Red Red Wine," a song written and first recorded by Neil Diamond in 1968.  It was not a hit.  A year later, the Jamaican singer Tony Tribe cut a groovy reggae version of the song...which inspired the English band UB40 to cut their own reggae version of it in a tribute to Tribe, which became a global hit in 1988.  Eventually, even Diamond himself got the message and started performing it in a reggae style.  And there's much more, including a 21st Century update of "Red Red Wine" entitled "Green Green Weed."  Check it out.
