Name this song - a 70s synth instrumental in 7/4

[Martin Gifford]

I'm writing a screenplay and it needs this synth instrumental that I vaguely remember from the 70s. It's kind of hypnotic and in 7/4, I think. The rhythm goes something like:

|1 2 3& 4 5 6 7& |

They are all 1/8 notes, I think, so it's a bit staccato. And the notes might be:

Ab Ab up to Bb down to Gb back up to Ab Ab Ab down to Gb down to Eb (i.e. 1 1 2 b7 1 1 1 b7 5 )

Tempo is about 105, I think.

Not much to go on, but that's all I remember.

TIA.

In case anyone comes across this thread/issue. The tune was not from the 70s and it wasn't a synth and the rhythm was wrong and it was only partly in 7/4. It was:

Music For A Found Harmonium by Penguin Cafe Orchestra.

Phew! Yes. Now what do we do with our lives?

Listen to more Penguin Cafe Orchestra.

Hmph! Not enough cowbell.

This PCO album haunted the alternative cafe worker of the 1980s and 90s. It was on constant looping repeat in all the local joints where busty English Lit students in doc Martens "worked" as waitresses, and at night when they put on their poetry events raising funds for crippled Symbionese lesbian donkey migrants, it was the interstitial music.
