"Sleep Sound In The Morning", also known as "Da Gutters O’ Skeld", "Out and In the Harbour," and all sorts of variations on "Sleep Soond I’da Moarnin'" is a tune originally from Shetland.
This is one of those tunes where the A and B parts are often played in either order. This version is from abcnotation.com (AABB) but Williamson gives it in reverse order (BBAA).
It was printed in Williamson's English, Welsh, Scottish and Irish Fiddle Tunes (1976), Cooke's The Fiddle Tradition of the Shetland Isles (1986) and others.
It was recorded by Abby Newton on Crossing to Scotland (1997), Alasdair Fraser & Natalie Haas on Fire and Grace (2004), Tom Anderson and Aly Bain on The Silver Bow, Boys of the Lough (1973) and others.
