Jack White returned to his hometown of Detroit on Thursday to kick off his “Boarding House Reach” world tour and celebrated the occasion by inviting his mom on stage.

The former White Stripes singer played to a rowdy crowd at Little Caesars Arena, delivering a nearly two-hour-long set, which included hits from across his 20-plus-year career in the music industry. But it was arguably White’s mother, Theresa Gillis, who stole the show.

Gillis joined the guitarist on stage to provide backing vocals and polka with him during a performance of White Stripes’ “Hotel Yorba”.

White shared photos of the heartwarming moment on his Instagram page.

Elsewhere in the show, White paid respect to the Motor City by trading in his polka shirt for a jersey of his former high school, Cass Technical High.
