Tim - me too!
The Beach Store was just a few yards down Ham Lane, where the flats are now (they were built recently, not rebuilt, on the site of an old garage.
And of course, the Beach Store was also where they stored the beach in the winter (according to some .....). It was last used in about 1985.

The Winter Gardens is now Carina's night club. There were folk dances in Tedbury's Café in the Winter gardens even before the festival started in 1955. Fred Tedbury encouraged song and dance displays in his café in 1969. Bubbyrat - was your friend Fred's son?

The bar-room of the Black Horse was on the left as you went in the main entrance - there was certainly informal singing in there in 1971. The bar itself was down the middle of the pub. The lounge was on the right and the folkies weren't encouraged to go in there! There was a yard in the back. In the 70s, a separate rom was built in the yard, and that was used for festival events later in the 1970s.
As Henry said, the Horse and Groom skittle alley was used as a festival venue, and the garden was full of people when the sun shone! The pub has now been replaced by flats.
The Beach Store was first used for song events in 1964.
The Old Forge was used for musicians workshops from at least 1966, and then for the Ballad sessions in 1969.

I wrote a book about all this ......
