Three original members of the Georgy Girl hitmakers - founders Athol Guy and Keith Potger, along with singer Judith Durham - have given their backing to the musical ahead of its launch in December (15).

Speaking at the cast unveiling in Sydney this week (beg24Aug15), Guy said, "The thing I love about it is the music deserves to live on for another 50 years - not necessarily with us doing it but this is a catalyst for pushing it back out. For us, we'd have to say it doesn't get any better than that."

Potger added, "There is a lot of drama in the musical - there are aspects to our personal life that will be portrayed in the musical."

Georgy Girl - The Seekers Musical is due to premiere in Melbourne on 15 December (15).
