Title Song

I just watched "Because They're Young" for the 3rd time over a period of many years. I really wanted to see and hear Duane Eddy play the title song but it wasn't there, just "Shazam" (brilliant)We did get James Darren's more insipid (to me) version of B.T.Y. but I missed Duane's twanging guitar. Can anyone help me? Was it cut or does my memory (and nerdy notes) play me false?
