Re. CCÉ recordings of English language songs, Jim Carroll wrote 'The fact that they have never included one on any album will do for a start.'

Well, here's two:

CL7 - VA - 'A Bar of a Song' - only two of the 20 songs of the album are in Irish.

CL44 - Bridget Tunney and Family 'Where the Linnets Sing'.

Additionally, Brendan O'Duill's album – 'Mo Roisín Dubh' (CL23) was half in English and half in Irish.

Add to the above the appearance of English language songs on several of the North American tour albums which make up a third of CCÉ's album releases.

As far as I recall Tom Phaidín Tom's eponymous album is the only full-length album example of singing in Irish that CCÉ has ever released (and that was 30 years ago!).
