We may be talking about 3 separate venues.
Firstly, the Golden Bear pictured in previous posts was not located at the "Waddling Dog" at the corner of Mount Newton and the highway.
The sleep walking "Bear" was the logo of the Travelodge chain. That is how the name of the pub became "The Golden Bear", and yes it was located at Beacon Avenue at the west end of the building as pictured in a previous post. Now if memory serves me correctly they did have live bands there and for a short while they also had strippers.
The Golden Bear met it's demise when the area was remodeled into the buildings that stand today. That's when the Charles Dickens pub came into being, but it is not exactly in the same spot of the old "Bear".
Now just to make life interesting, there was a Cabaret on the property that opened in 1975 and was located on the west end of the Travelodge building. That is where the really wild live music and partying happened. That building is long gone. Here is an rather humorous old advertisement of the "Sour Grapes" an American Band that opened the venue.
Please keep in mind that the facts presented above are subject to change and correction as there were a lot of drugs and alcohol involved in the research that started 40 years ago.
