Have a listen to 1:33 to 1:59 of TISM’s Greg! the Stop Sign (1995)…
Now have a listen to 17:14 to 18:00 of Andrew Lloyd Webber’s Variations (1978)…
And finally, listen to the Shadows’ FBI (1961)
There’s quite a few references online to TISM quoting the Shadows, but I haven’t seen any noting the intermediate Andrew Lloyd Webber step that baroque-ised the middle bit.
On a side note, have a good listen to the Variations. There’s some very 70’s bits in there (four on the floor disco and jazz flute anyone?), but there’s also some damn good re-interpretations of the classics.
