and Elephants have in common?
Well they are all cockney rhyming slang for the state of inebriation. Brahms (and Liszt) is quite a common rhyme for pissed (British slang for drunk) as is Oliver Twist.
Elephants? Well this is short for "elephant's trunk" rhyming slang for drunk.
There are quite a lot of others, Schindler's List is another. One I've never heard said but have seen written down is "Newton and Riddley" rhyming slang for "tiddley", this seems funny as Newton & Ridley is the name of the brewery on long running British soap opera Coronation Street.
