This tune is from a book of tunes by Paul Wilding for 6 and 7 string lyres, Its the only tune book I know of and can recommend to lyre players. The book includes sheet music and tab.
The Tab is different to what I use on lyres, Paul uses a type the numbers reversed like a harp (and like the Kantele tab I use) An easy task to read, or write out again as you learn tunes.
