Here's a motif you might try: Fiddlers often dedicate tunes to each other. Thus you could have a circle based on:

Jerry Holland wrote Brenda Stubberts Brenda Stubberts wrote Rannie McLellans which Natalie MacMaster recorded and her uncle Buddy MacMaster, Member of the Order of Canada wrote ? ...John Campbell wrote Sandy McIntyre's Trip to Boston, Sandy McIntyre wrote Scotty Fitzgeralds Jig, Winston "Scotty" Fitzgerald wrote ?

As you can see, you should never have let us begin...
