I need to be able to identify some pieces of music, or rather the
orchestra(s) which played them. I have uploaded samples of the pieces
to http://www.apple-juice.co.uk/Googlestuff.mp3. It's a 5MB .mp3 file.

The quality is poor, due to the age of the tape, which is at least 32
years old and probably older. Also on the tape are recordings of
Swingin' Safari-era Bert Kaempfert, so I suspect this stuff is of the
same vintage.

I can't identify the orchestra - I think, but I am not at all sure -
that all the pieces might be by the same ensemble. I'm not sure what
all the pieces of music are either, though one of them is a frankly
stunning essay at the last movement of Beethoven's Ninth, and I
wouldn't be surprised to discover that the persons responsible had
been arrested for it.

The orchestration of most of the pieces seems to be: electric bass,
high in the mix; electric guitar; some sort of very tinkly
harpsichord-like instrument; strings; woodwind; drum kit;  female
voices.

I am fairly certain that the first four pieces (including the
evisceration of the Ode to Joy) are by the same ensemble. I think that
the fifth, sixth and seventh are by the same group, though whether
it's the same as the first I am not sure.

If you can identify the actual pieces, that would be great, but I
don't think they are particularly obscure, and it's the groups that
I'd really like to pin down.

It's probably not a full-time ensemble like London Symphony.  It
sounds, on 2 hearings, like a core group of musicians (bass, guitar,
keys/synth, one of them probably the composer/arranger) with hired
freelancers to fill out the strings, etc.  I can't imagine that the
material was recorded to be a stand-on-its own album as much as being
recorded to be filler/background music for film, tv, weather channel,
grocery store, etc.

I wonder that myself. Someone pointed out that ome of it sounds
uncannily like Love is Blue-era Paul Mauriat, but I am pretty sure it
isn't actually Paul Mauriat.
