Out Of The BlueElectric Light Orchestra
Side three of the release is subtitled Concerto for a Rainy Day, a four-track musical suite based on the weather and how it affects mood change, ending with the eventual sunshine and happiness of "Mr. Blue Sky". This was inspired by Lynne's experience while trying to write songs for the album against a torrential downpour of rain outside his Swiss Chalet. "Standin' in the Rain" opens the suite with a haunting keyboard over a recording of real rain, recorded by Jeff Lynne just outside his rented studio. Also heard at the 0:33 mark of the song, which marks the beginning of The Concerto, is thunder crackling in an unusual manner voicing the words "Concerto for a Rainy Day" by the band's keyboardist, Richard Tandy. At around the 1:07 mark, the staccato strings play a morse code spelling out "ELO". The band used the song to open their 1978 World Tour Out of the Blue concerts. "Big Wheels" forms the second part of the suite and continues with the theme of the weather and reflection. Apart from its inclusion on the Out of the Blue album, the song has never appeared on any of the band's compilations or as a B-side until 2000, when Lynne included it on the group's retrospective Flashback album. "Summer and Lightning" is the third song in the suite. The raining weather theme is continued throughout the track though the mood and lyrics are more optimistic. "Mr. Blue Sky", an uplifting, lively song celebrating sunshine, is the finale of "Concerto for a Rainy Day" suite. Again, the Vocoder is used at the end of the track where, at the 4:54 mark, one can hear "Please turn me over" as it fades out. It is the only piece from the Concerto to be excerpted as a single.
