The only time I ever I saw Queen was at this concert. I distinctly remember Dr May breaking a string during "love of my life". Obviously there can be no hiding that. He did his best but ... well you can imagine.
I had always thought that the "DVD" was comprised of both nights footage, but someone told me they only filmed the second night.
They practised a bit of filming on the first night - aren't there four full tracks on the DVD? Even if they didn't have any 1st night LOML to potentially drop in, they could have cut around it, and we all know how easily replacing the audio would be.
