Two of the Clancy Brothers, Liam and Bobby Clancy, make guest appearances on The Girls Won't Leave the Boys Alone. They both perform "Freeborn Man of the Traveling People" with Bobby's son, Finbarr, and daughter, Aoife Clancy, a former member of Cherish the Ladies. This was the final recording of any of the Clancy Brothers together. Liam Clancy also sings "The Jolly Beggarman" with Arlo Guthrie on the album. The Clancys' former singing partner, Tommy Makem, appears with John McCutcheon and Tom Chapin on the song, "Rambling Irishman."
Other guest artists include Paddy Reilly, Luka Bloom, Pete Seeger, fiddler Brendan Mulvihill, banjo player Eric Weissberg, flutist Matt Molloy, and Liam Ó Maonlaí. In the second half of the recording, the Ladies pay tribute to their families by playing a rendition of "The Queen of Connemara"[2] accompanied by their fathers and brothers. This album is a departure from the group's previous dance-tune-based recordings, but the quality of the singing is regarded as very good throughout.[3]
