This is a request that I got for an ELO (Electric Light Orchestra) 1978 hit. At the time, Jeff Lynne broke out of a creative block and invented a musical superhero that many of us learned to relish and sing along with. It was originally recorded in Munich, Germany and the electric voice of this superhero was inspired by Sparky's Magic Piano, an old children's record. In the original song, Mr. Blue Sky introduces himself in the second bridge, via a vocoder. "Thou shalt not number seven" was the original working title and this song is considered one of the most uplifting or happiest songs ever recorded. It was used in various ads for multiple companies, in movies, and on spacecraft (space shuttle Endeavor & space shuttle Atlantis) as the wakeup call for the astronauts. A piano solo version of this song may not do it justice, but it is a reminder of the original that people enjoy when I play at Mayo clinic.
