He sang 'The Jervis Bay' and one about PQ17. I wrote both of them down, unfortunatly my note book, 'long with my watch & tobacco pouch , were stollen later in Lourenco Marques. All I can remember was the tune was "The church is one foundation" and one couplete......

Ocer the years I've racked my brain trying, without success to remember any other bits.
