G'day,
The Everly Brothers version of "Rose Connolly" is on the "Bringing It All Back Home" double CD, a Hummingbird production for BBC Television (Northern Ireland).I also have a version somewhere on an old Peter & Gordon album.
As I heard the story of "Sally Gardens", Yeats needed a song in a hurry for some function & wanted to use "Ye Rambling Boys of Pleasure". When he couldn't find the words in time he wrote "Sally Gardens", set to an older tune.
Cheers,
Alan
