“Dear Brian,

Thank you for a fantastic disco at our wedding in September.  All I wanted to do was dance and I was really happy when I (eventually) got some people on the dancefloor.  My mum certainly enjoyed herself!

It was really good to meet you before the event - we both instantly liked you and knew you’d do a great job for us.  I’m already thinking of more parties to book you for - perhaps some 30th birthday parties in the next few years!!

Thank you so much,

Rachel & Steve”
