Peta Webb's 1973 TOPIC LP, I HAVE WANDERED IN EXILE , includes The Moorlough Shore and The Lovely Banks Of Lea, as well as I Have Wandered In Exile, all of which are Irish emigrant songs full of the longing for home. This is a great LP by a great singer with a great voice who sings with total sympathy for the songs - certainly one of my desert island discs. The LP has been re-issued by a Japanese company as a CD under the series title of British Folk Paper Sleeve Collection and is distributed by Vivid Sound Corporation, VSCD-831, perhaps Camsco can get it?
More readily available is Kate McGarrigle's song Jaques et Gilles about Canadian migration but also touching on Irish emigration.
