The band have vowed to rescheduled 10 US concerts later in the year - likely with a guest vocalist - and Almqvist is throwing his hat in the ring for the gig after the Swedish outfit supported AC/DC on an Australian tour late last year.

Almqvist writes on Facebook: "Very sad to hear Brian Johnson can�t do a bunch of AC/DC shows due to health problems. That man is a legend. I would like offer my sincerest well wishes and get wells, and if any help is needed, I put my foot forward and say: Here I am.

"I have many many years of experience rocking the world's biggest stages and, according to others, I am the greatest frontman in rock, plus judging from the reaction in Australia your crowd already seems to really like me. Plus, I have already been singing those songs since I was six-years-old.
