Dear Mark,
We just wanted to say a huge thank you for making our wedding such a brilliant day. You were incredibly friendly, knowledgeable and professional when we met you in the run up to the wedding and we could see you wanted to ensure all the lighting was just as we wanted it and that you played exactly the kind of music we wanted. On the day, you were totally brilliant. All ready and set up before we knew you were even there and lots of people remarked on how great the music was - plus the manager of the venue said he'd never seen so many people on the dance floor there before! So many people have told us what an incredible party it was and that was definitely partly down to you!
We were really, really happy with how it all went off and wouldn't hesitate in recommending you. In fact, you gave us such confidence, we were already recommending you before the actual wedding!
Thanks again.
