No can't really think of any either. However I've often thought that the two genres do have a lot in common. Particularly lovers rock & trad English folk songs - great melodies & fine singing etc ... however, on the cpl occasions that it's been tried (to reggae-fy English folk) it always seems to come off as a bit twee somehow. Jah Wobble (not exactly reggae I know) did an album called English Roots Music, which as I recall was not bad but certainly no classic. Does have a dub version (& non-dub vrsn) of Blacksmith on it. And you couldn't really dub up many existing folk recordings as there's usually not many instruments being used & certainly not too much bass & drums ... though I guess it might be fun to try the Morris On recordings.
