If written, I'd personally go with either
We would like to thank Norma Pope, our Wedding Coordinator; Caroline Carr, the/our Entertainment Director; and Evan Kolher-Camp, who played the pipes, for helping to make this day so special.
or
We would like to thank Norma Pope for coordinating the organisation, Caroline Carr for taking care of the entertainment, and Evan Kolher-Camp, for playing the pipes. Thank you for making this day special.
If you don't want to rephrase, then you'd have to put the commas like so:
We would like to thank our Wedding Coordinator, Norma Pope, Entertainment Director Caroline Carr(,) and Piper Evan Kolher-Camp, for helping to make this day so special.
'Norma Pope' is a non-restrictive clause, so it's enclosed in commas. The comma after Carr depends on whether you believe in such commas: do you by "bread, butter, and eggs" or "bread, butter and eggs"? |
