The band axed a number of shows after the rocker fell sick on tour, initially fearing he had been struck down with altitude sickness and later revealing he was battling a lung complaint.
Lemmy took time off to recover, but made a comeback on Tuesday night (08Sep15) by returning to the stage for a show in St. Louis, Missouri.
After the concert, the rockers posted a number of pictures of the event on the band's Facebook.com page along with a message thanking fans for their support.
The note reads, "St.Louis!!!! St.Louis St.Louis SAINT LOOOOUUUIIISSSS!!!!!! (sic) How lovely it was for Motorhead to kick every single one of your a**es tonight eh?!!!!!!!"
