A broad Irish accent saying McCarthy would sound like McCartey.
And not such a big step to McCartney?
Especially when heard by English ears 
It is something we need to worry about when trying to find records for Irish, Welsh and Scottish people.
Then there's a lot of variation in the anglicisation of names from these places (and the reverse too).
It all adds to the fun!
What fun?!?

P.S.: I too enjoyed the van Tulleken episode very much
