Thank you both very much for the information.   

I'll check out the score for La prise de Foudroyant, and I hope to be able to either get a recording or someone to sing at least some of it on the night.

The battle off the Isle of Man was 28th February 1760, and coincidentally Le Foudrayant was captured on 28th February 1758, after a three-day battle, subsequently being refitted as HMS Foudrayant.

Gura mie mooar eu - Merci bien!
