DQ dualmono
Dancing Queen in dual mono
Left Channel : Dancing Queen vocal mix edited to fit the released version
Right Channel : Dancing Queen from the TYFTM Box Set mixed to mono using Audacity
I was making a quadraphonic version of the track, and since YouTube does not support any discrete surround sound here's a poor mans version with the left channel being a mono mix of the front channels and the right channel being a mono mix of the rears.
There are a few edit points which can be improved upon, and in some cases the edits I've used are the wrong ones, but on the whole it's an interesting listen.
