Yeah I play this. It took a while to pick out all the correct notes in the rundown towards the end. Watching live ELO wasn't much help as the bassist has his bass strung upside down but I prefer to always refer to the records first and foremost.
It is a good bass line. Our community jazz band play a version - page 1 was fine, page 2 was just one long walking bass line that took me a couple of years before I could play it.
