Aerosmith star Tom Hamilton has quit the band's Australian tour due to illness.
The bassist has pulled out of the rest of the group's shows Down Under and jetted back to the U.S. after falling sick with a nasty chest infection.
Musician David Hull, who has stood in for Hamilton on previous Aerosmith tours, has been flown in to take his place.
Hamilton will rejoin the band's ongoing world tour once he recovers.
Aerosmith have two dates left in Australia - in Brisbane on 1 May (13) and Melbourne on 4 May (13).
