READ NOW�I think the four of us have a particularly good chemistry in our voices together, so I think it will be amazing.
"There's a bunch of songs that we all sing together, like Nowhere Man and What Goes On, that I think will be a really exciting part of the show. It will probably be my favourite part of the show as well."
Gawenda said he grew up listening to The Beatles and was looking forward to doing something outside of Husky.
"I think it will be a nice little healthy break for me," he said.
�It will be nice to be involved with something that just kind of sweeps me along and I can just focus on the songs and getting them across in the best possible way and that's it, I don't have to think about anything else.
"In a way it's a kind of easy and fun job for me because I know these songs and all I really need to do is sing them."
Gawenda said performing hits such as Norwegian Wood, Yellow Submarine, Tomorrow Never Knows and Eleanor Rigby "feels like big shoes to fill".
"I hope people really enjoy it and have a great experience and connect with the songs," he said.
"I think that's always the aim whenever I get up and sing " to try my best to deliver the songs so that people can connect with them and these are such great songs, so easy to connect with, so I�m hoping that I don't stuff that up.�
