Retro YouTube- 1950's Hamburg Red Light District

Very interesting short from Weirdo Video. From the description:

Let us reminisce of beer celebrations held nightly during the 1950's and 60's in the Teutonic hamlet of Hamburg.

A phenomena that grew from a chronically disaffected population of post-war Germany, you may never see so many irretrievably plastered people in one place at one time ever again.

It is in the legendary Rathskellers of Hamburg that the early Beatles honed their craft and showmanship before they broke big in the early 1960's, grinding away in multiple sets-per-night while fueled on copious amounts of beer and cheap speed.
