Another excellent puzzle, this one by Skylark who, by all accounts, is a relative newcomer but she did herself proud with this fine effort.
I really didn't make things easy for myself by being convinced I was looking for the name of a 4 piece band - it was only when the same phrase kept coming up in word search engines that i finally twigged. Then, to make matters worse, I stupidly mispelled a word which meant finding the fourth name was way more difficult than it should have been.
