Here’s a promotional photograph from the February 18 1952 edition of the Toronto Daily Star of a couple who made music with bells:
Google searches turned up very little on either Art and Mabel Guinness or the Video-ettes. It didn’t help that a man named Arthur Guinness founded the Guinness beer empire in the 18th century. Just in case, I checked the Guinness family Wikipedia page to see if the Art Guinness in this photograph was a descendant. He appears not to be.
I did find this reference to the Video-ettes in a Bowmanville newspaper in 1950. This article stated that the Guinnesses were from Toronto, so I looked them up in the Toronto city directories. Sure enough, the 1952 directory listed Arthur M. Guinness as an entertainer and living on Bessborough Drive in Leaside; the 1955 directory had the same entry. But then, like many entertainers before and since, he got a day job: he was listed as an employee at the CBC in 1956, and then was working as a sales rep in 1957. By 1962, he was president of McLean Merchandise Sales.
