Music Used In Youtube Laserium Film

[AndiFlatland]

I was watching a clip on YouTube about Laserium, the 70s lightshow display. At one point in the soundtrack, there was a piece of music which is very familiar, and I'm sure I've got it somewhere in my vast collection - but I cannot think for the life of me what it is. Can anybody identify it?
You'll find the clip at

Then move the time cursor to 4:26. The music clip only lasts about 20 seconds.

It's "Pepper Box" by The Peppers.

It was a hit in 1974.
I mis-remembered the title as Pepper Pot.
Around that ttime it was quite common for instrumentals to do well in the singles charts. It hardly ever happens now

Yes, yes!!! Of course it is - thanks so much!
I've been running that little clip round my head for the last 3 days, and getting nowhere. It could have taken me a very long time to back-connect it to the main synth tune.
Isn't there supposed to be some website where you can sing in the notes from a tune that you can't identify, and it'll match them to all the possibilities in its database? The trouble with instrumentals is that... there are no words! (To state the glaringly obvious). How many times have I had a bit of a tune running round my head, often from TV documentaries, which might be the Shadows, or the Ventures, or any one of a legion of other 60s guitar instrumental bands, and had to pull out disc after disc to check all the possible tracks? Often to find that I'm looking in completely the wrong place, and it turns out to be an instrumental break in an otherwise vocal song!
Thanks again.
