Though never a celebrity, I had a stage name. In radio back in the 60's, the station that I worked for had three featured disc jockeys and they were required to use company names. When I arrived for my first shift I was told they already had a Tom, and a Dick, so I would be Harry. The last names assigned to us were, Brown, Bell, and Scott.
One of the earlier Harrys had come from WMEX in Boston, which was one of the nation's top Rock n Roll stations in the 1960s. He was required to use the name 'Fenway'. The Fenway is a section of Boston, known mostly as the site of the Red Sox field, Fenway Park. Over the history of the station there were more than 20 guys who used the name Fenway.
The station was a 'T-N-T' outlet...meaning the disc jockey would give the time after playing one record and then the temperature after the next. My pal played a Jerry Lee Lewis 45, then said, "It's 9:15 in Boston and the temperature is 76 degrees."
He was fired right after his shift. When he asked why he was being let go, the owner of the station said, "because you gave the time and the temperature together."
