I caught the programme a few days back when it was shown on SkyArts. It was very interesting, with some great archive footage, though I think that Mr Collins' versions of the songs all paled compared with the Motown originals and was somewhat sceptical when one of the Funks said that he thought the re-creation of "Heatwave" was better than the original.
I didn't realise that Phil Collins was considered to be Marmite, he's one of those artists that I can either take or leave and I don't have an opinion one way or the other. Obviously he's a huge Motown fan of course.
