McDougall has issued a statement.
Tonight Alive singer Jenna McDougall has revealed her health is the reason behind the band axing a show in Melbourne tonight.
After the Sydney outfit announced the gig at Arrow On Swanston has been cancelled due to "unforeseen circumstances", McDougall took to her personal Instagram account to explain.
To our Melbourne fans and ticket holders of the AA show at Arrow on Swanston, unfortunately due to unforeseen circumstances we will not be able to perform for you tonight. As you know we love and cherish our time with you, so our apologies come from the deepest place possible.
