the line at the end of the verses is "slán libh, a chairde, slán libh"

I'm listening to Brian Moore singing these lyrics

It's the closing track on an album "Patriotic Names, Songs of Tribute to Irish Patriots!
Brian Moore is also the singer of Slán Libh on the 101 Beautiful Irish Ballads album. Does that mean that Mudcatter "Belfast" was Brian Moore? (!)

and here is the Behan "Make Yourself at Home" Topic recording I'm not sure if the lead singer is Dominic Behan or if this is an album of Behan songs? I wonder who else is playing and singing with the lead singer. The full "slán libh, a chairde, slán libh" line is sung.

the lines are set to a lovely air
