Transcribing the end credits for Only the Good (for a university project), I noticed another blunder:
Ricky Grover is credited as "Ricky Glover". Hmmm.
I’m not sure how he’s credited for the rest of the series and haven’t the time to check. But I should imagine that it has something to do with the casting director being Linda Glover. Or not. (I was only guessing.)
And not wanting to make myself look like an arse in getting this post wrong, I’ve just checked on TOS to find that he’s credited there as "Ricki Grover". Extraordinary.
