This clip dates from the summer of 1973 and features DJ Ron Robin on WVBF FM ( Electronic Mama) from suburban Boston. A good example of their Top 40/AOR hybrid format. There were a number of FM stations in the US around 1972-74 with a similar format.
The playlist includes a few pure AM singles, some FM friendly singles and also an album cut by the Stones. Steven Tyler from Boston’s own Aerosmith calls in from a concert location near the end of the clip. Their single Dream On had just taken off and was a hit huge in Boston on it’s initial release in 1973. The song became a much bigger national hit upon it’s re-release in 1976.
