If it helps: Barry Adamson, Walk on fire from the 2008 album Back To The Cat (Mr Duff does like that album, I did wonder if it was coz I suggested BA ages ago) it's at about the 16 min mark
Thank you for this one. Do you also know the song at 08:28, the one that joey mentions in the first post?
Another one is at 19:55, when CH with Jess sit at the table. And I think it continues at 22:47 when Moz kisses Tilly. It's called "My Guy"
and looks like it's very old and have been performed by many people. But I can't find just this performer.
