I want to modify my artistsort and composersort actions (simple reversed names of artist and composer) to ignore additional artists/composers.  
I use:  
$regexp(%composer%,(._) (._),$2',' $1)  
Which converts:  
Big Bubba  
into:  
Bubba, Big  
and seems to work with most names including initials. I can't make it work with multiple names however. I decided the easiest way was to chose the major artist/composer and include the rest in brackets then include an expression to exclude the bracket contents in the action to reverse the name. I found this:  
,(.+?)  
However I can't figure out where to place it in the expression.  
I would prefer a complete expression that sorts by the first artist/composer and ignores the rest. For example:  
Artist: Big Bubba, Miss Piggy, Donald Duck  
Into:  
Artistsort: Bubba, Big

Try "Format value" for ARTISTSORT  
Format string: $regexp(%artist%,'(.+?) (.+?),.\*$','$2, $1')

**ARTISTSORT \<== $regexp(%ARTIST%,'(.+?)\s(.+?)(,.+?)\*$','$2, $1')**

Thank you. They both seem to give the intended result. Much appreciated.

Actually this works better because it also works with single artist sort so I don't have to change actions.  
Regards

EDIT: Is there a way to make this work with artists that have initials?  
For example:  
Artist:  
Big B. Bubba, Miss Piggy  
Artistsort:  
Bubba, Big B.

At present it formats to:  
B. Bubba, Big

Regards
