We had William and Mark as the entertainment for our wedding in November. I had only read reviews and seen clips on his website but he FAR exceeded our expectations. All of our guests - without exception - loved him and he even got the most unlikely candidates up dancing! It was so lovely to have live music and William and Mark are great musicians who really know their stuff. William even let me sing with him! Rob and I had the most amazing day and it was made absolutely perfect by William - so a massive thank you! We cannot recommend him highly enough!
