Mick Smith's got it, he has Searling's old copy, it's a one sided disc with an orange label, Breakthrough is in a straight line across the top, I was looking at it about a month back. The reissue has a much fuller production and lasts a good 25 seconds longer. I persoanlly prefer the second version. I found Charles Diamond himself about 2 years back, his missus wrote to me for some reason, can't quite remember now. I put them in touch with Kev Roberts
