Irish-Americans John Haggerty and Mike DeAngelis have been performing Irish music together since 1979. In 2013, they founded their newest band, GET UP JACK, a culmination of nearly four decades of musical performances together and with other well-known bands, playing in the US and Ireland.  John and Mike have had the distinct pleasure of sharing the festival stages with their original musical inspirations: the Clancy Brothers, Tommy Makem, and The Wolftones, as well as their more contemporary influences: The Saw Doctors and Great Big Sea.  Drawing from classic Irish folk sound, GET UP JACK merges today’s high energy Irish music with impressive vocal harmony and unexpected musical talent. GET UP JACK is at home playing in a neighborhood pint-swinging pub or performing on a festival stage to a dancing crowd of thousands - and every venue in-between.  Old and young alike enjoy the moving beat or mournful ballad from these seasoned showmen, who have also shared the same festival stages with Gaelic Storm, Eileen Ivers, Solas, Black 47 and The Young Dubliners, to name a few.


GET UP JACK has released three albums that have been critically-acclaimed and award winning.  Their live album, “Alive and Well, Volume 1” was named 2015 "Album of the Year" by Celtic Radio, with their version of “The Spanish Lady” being voted “Traditional Song of the Year”.
