Thank you, Tim Horwood.  The glades around Windsor Castle are
inspirational.

The Windsor Castle opera could well be the answer.  Quick Search revealed
that its Overture has been recorded by Roy Goodman with the Hanover Band
(Hyperion CDA 66528), along with the Symphonies 101-2.

One can even listen to it from the Indiana University Cook Music Library -
if one can get to one of their computers.

And now to check out the work.  If there is anything like a Serenade to be
found, I shall be sure to let you know.

Again, Thanks to all for responding.
