Just a line to say a big thank you for your hard work and great singing on Saturday, we have had very positive feedback and everyone enjoyed it. I hope we will be able to work together again, perhaps next year."

Maureen Cook, CPC Kent.

"On behalf of my wife and myself may I take this opportunity to thank you for superb set you performed at our wedding on Sunday 9th October 2011. You are a true professional. From booking all the way through to the show itself you were completely flexible and fitted in your setup and sound tests around us and our plans to minimise disruption to our big day.

As you know we performed our first dance to you singing "hold on". Wow what a fantastic honour it was and a cracking way to start our married life.

Oh just in closing, the feedback we have received from our guests is extremely good, everybody loved you and your performance.

Many thanks."
