Their rendition of "In The Summertime" was not issued in the UK presumably because Mungo Jerry's version was such a big hit that the Mixtures would have lost out to it. Mungo Jerry's version was not a hit in Australia at the time, so the Mixtures grabbed a hit with it there.
When I bought this in 1971, my copy came with a three prong centre and yet every copy I've seen since has the large hole. Does anyone know why so many were pressed in this way for the UK market?
I've since got a solid centre copy which I think is pretty unusual?
ps. The B-Side is brilliant!
