I made some corrections to my last comment... The bar where Beatles sang when they came out was called The Cavern. I typed the wrong letter before. Sorry. Bars are still the same as they were decades ago, bars are almost unchanged. Ask passers-by and they'll be easy to find. Order a beer, sing and dance together with the music on the stage. Almost everyone can sing "hey jude" and listen to Beatles before going. It's really like going back to the last century. Attached is a picture of Cavern.
