Jimmy Carmichael was also a singer and he gave a number of songs to Sam Henry. The ones listed by Roud are

THE HILLS OF TANDRAGEE
JOHNNIE HART
UNDER THE SHADE OF A BONNY GREEN TREE
FAREWELL TO SWEET GLENRAVEL
KELLSWATER
LOVE'S PARTING or JAMIE AND MARY

Love's Parting is probably better known as I am a Youth That's Inclined to Ramble. Fantastic song. And Gina Le Faux learned Kellswater from him. Alas I never heard Jimmy play and I never heard him sing either. But for a short list of songs that would sure take some beating.
