Just found an mp3 of what was my favorite song when I was about 12 - Neil Sedaka's I go ape. It has a great sax solo and I wonder if anyone knows who? It's not listed in John Laughter's excellent book as far as I can tell from a Word search.
This video will give you an idea - but whether that's the original player I have no way of knowing:
I'm pretty sure the sax player over the end credits is Stan Getz - obviously slumming!
