Stuart Wood, Les Mckeown and Alan Longmuir announced the big news on Tuesday (22Sep15).

A joint statement from the trio reads: "We have a very special Christmas present to all the fans that have kept the faith with the band over the years."

The group formed in the late 1960s and split almost 30 years ago after selling over 120 million records, hosting their own TV show and hitting the top of the charts all over the world with songs like Bye Bye Baby and Shang-a-Lang.
