I wondered whether the choral work Kim Patrick Clow remembered hearing is
Mozart's incidental music to Thamos, King of Egypt K345 (no, that's not a
typo, it's Thamos, not Thomas).  The recording I have on LP is a 1973 one
on Philips conducted by Bernhard Klee and since re-released on a 2-CD set
with other theatre music as part of the Mozart Edition.  It uses as an
overture the Symphony No 26 K184.  Not all the movements have a choir.
There are later recordings by Harnoncourt on Teldec, and by Eliot Gardiner
on Archiv.  I'm not aware of one by Hogwood.
