Jack White is currently in the middle of a European leg of concert dates supporting his latest solo album, Boarding House Reach. Tuesday marked a particularly special stop of the tour, as White played a show in his mother’s homeland of Poland. It just so happened that Teresa Gillis, aka Jack’s mom, was in the house at Warsaw’s Hala Torwar venue to celebrate her 88th birthday, and her seventh son brought her out so the crowd could regale her with “Sto lat”, the Polish b-day song.

Jack’s tour of Europe will keep him occupied for the rest of the month. He’ll be back on this side of the pond for a North American trek come November. He also recently revealed plans to reunite with The Raconteurs for their first new album since 2008’s Consolers of the Lonely, which is expected next year.
