Hello Margret.
Firstly, I thought I should tell you that a copy of David Mulhallen's review of your CD has been placed on FOLK AUSTRALIA.You can see it in the REVIEWS section here: http://folkaustralia.com/

Not sure if it means Denis Gibbons - I found it spelt that way on a website! Here's an interesting reference to the FOUR GUARDSMEN taken from, of all placed, a copy of Hansard (April 6 2000) in 2000:

"Mr Jack Neary, AM, OBE. was a giant of the Australian entertainment industry ... Jack Neary was a young policeman when he formed a quartet called The Four Guardsmen, entered it in Australian Amateur Hour and won. Success followed, and the quartet became national stars of radio and the Tivoli circuit.

Jack moved from entertainment to managing entertainers. Bobby Limb, John Laws and the orchestra leader Bobby Gibson all began their careers with Jack. Later he extended his activities, started booking overseas artists to come to Australia and moved into television production and film making. Jack brought many famous artists to Australia, including Winifred Atwell, Harry Secombe, Dave Allen and Jack Benny. He was involved in touring the von Trapp Family Singers, but the highlight of those years was his signing of the Beatles for their Australian tour. ..."
