I fixed/standardized the spelling & linked the pages. That was it. The pages don't auto-link if the spelling isn't identical. Patti Glick is an established artist with no other presence here. Her IMDb page says she's an actress who also does voice work. So...

Established artist + familiar dementia artist = collaboration. Separate linked pages.

Artist + 'featured' performer' (ex: "Crotch Hound, The Circumcising Dog") = NOT a collaboration. One artist page.

As for the spelling, if it actually is "3 Guys From Hollywood" and not what's there, I'll just change it back. One of Wayne's more recent site updates made this easy to do. Show playlists will usually change when artist/song pages are altered, so you don't have to do anything.

...Admittedly, I've just gotten up from an unplanned nap (damn meds), so if I missed anything blatantly obvious, which is possible/likely, just mention it & I'll sort it out.
