FLEETWOOD MAC announced via Facebook on Saturday that they have cancelled the remainder of their massive world tour, including legs in Australia and New Zealand, while bassist John McVie undergoes treatment for cancer.

An official statement from the band:

FLEETWOOD MAC who has just completed the European leg of their phenomenally successful worldwide tour has announced the cancellation of their upcoming 14 date tour of Australia and New Zealand.

John McVie, one of the co founding and original members of FLEETWOOD MAC is now scheduled to be in treatment for cancer during that period of time.

We are sorry to not be able to play these Australian and New Zealand dates. We hope our Australian and New Zealand fans as well as Fleetwood Mac fans everywhere will join us in wishing John and his family all the best."

FLEETWOOD MAC released their first new music in 10 years back in April, a four-song EP entitled Extended Play.

Guitarist Lindsey Buckihgham notes the new material as “the best business we’ve done in 20 years.”

Critics seem to disagree, however. Stream Extended Play down below.
