Alan Esdaile… Did Dandy Livingstone appear instead of Nicky Thomas?
Sheila Maile… Remember their song. Your my pigeon your my dove.
Jan Warren… Waaheyyyy, Rubber Band!! 
Nigel Sherwood… Nicky Thomas appeared
Sylvia Sinden… Did Katie sometimes sing as a backing singer for Eric Clapton?
Alan Esdaile… Yes she did Sylvia and some great clips on You Tube.
Mick O’Dowd… Mac & Katie were a great brother /sister act. Very talented and great voices. Unfortunately they were saddled with cheesy pop songs to record which never let them express their true talents. Katie became a backing singer for alot of acts in the same mould as another wasted talent Madeline Bell. I remember seeing Nicky Thomas on The Pier Alan but i’m sure he was headlining.
Martin Richter… darn – missed it
Peter Fairless… Their hit from 1973 (in the Netherlands!) was Song For Everybody.
David Edwards… Katie became a much in demand backing singer and was with Van Morrison for a number of years
