Queen’s Brian May and Eddie Van Halen collaborated on a project nearly 40 years ago. May told Total Guitar that it happened during a time that members of Queen had taken a break from each other in 1983. He was spending time in LA and out of the blue, he called Van Halen and told him of his idea and said, “My little boy had been watching this science fiction series and I always thought that the theme tune for it would be a great vehicle for all-out guitar playing. And Eddie said, ‘I’m up for it!’ So that was the beginning.”
May also recruited REO Speedwagon’s drummer Alan Gratzer, Rod Stewart bassist Phil Chen, Queen keyboardist Fred Mandel and Queen’s drummer Roger Taylor.
According to May, he had constructed the basic tracks, leaving room for Van Halen to do his thing. From there, May and Van Halen discussed what else could be done and they decided to jam out some blues.
