Four Men and a Dog are playing a gig at Cultúrlann Uí Chanáin, Derry, Northern Ireland on Friday 3 Feb, part of the Imbolc festival at an Cultúrlann. Cathal Hayden (fiddle and banjo) and Gino Lupari (bodhrán) are still in the group.

I think the line up is somewhat flexible. Sometimes banjo player Gerry O'Connor plays with them (I saw him with the band a year or two ago anyway). The band's facebook page cites this lineup: Donal Murphy, Cathal Hayden, Stephen Hayden, Gino Lupari, Kevin Doherty; and gives the first gigs of 2017:

Friday Jan 27th: Glasgow Royal Concert Hall, 7:30pm, Celtic Connections Festival. [Four men and a dog & Imar)[Imar will be at Imbolc fest Derry on Wed 1 Feb]
