The short answer is no and my Ark tape disintegrated long ago so I can't play it. However, Miles Weatherill & Sarah Bell was originally a Halliard song on which Dave Moran did the lead vocal. They got it from a John Foreman Broadside and the tune used is a joint Nic Jones / Dave Moran composition. Later, Nic changed it around a bit and my guess is that the fade-out tune was one of his own. It isn't used on The Last Goodnight recording from 1968 so it's fair to assume that it developed and got incorporated during the 70s as a result of performance.
