Oh God, I forgot about this record, but basally this old lady in the 1960s, who was called Mrs Miller, made a pop record full of covers of other songs in such an odd way.
It's certainly not the worst record I have ever heard, but I won't like to replay it for a while.
While the Mrs Miller record was kind of bad crap, a few months back I uploaded an album call "The Worst Demo Tape Compilation In The World Ever" that is full of so many terribly-funny demo tapes - it kind of reminds me of 'Don't Buy This' by Firebird for the ZX simply because of how the people made the end product did such a terrible job.
