From the newspapers.
Not sure if it's the correct one but there was a drapery shop called The Cut Price Drapery on Connaught St in 1961
maybe the same shop as the The Cut Price in 1975 Faulkner's drapery shop Connaught St. failed to sell at auction but was sold to an undisclosed buyer later. Faulkner's were moving to a different street.
Could the nightclub be Daffy's Club, Connaught St, I see ads with DJs named in 1971.
No joy with the barber.
