Sky

The sky (or celestial dome) is everything that lies above the surface of the Earth, including the atmosphere and outer space.

In the field of astronomy, the sky is also called the celestial sphere. This is viewed from Earth's surface as an imaginary dome where the sun, stars, planets, and the moon are seen to be traveling. The celestial sphere is conventionally divided into regions called constellations. Usually, the term sky is used informally as the point of view from the Earth's surface; however, the meaning and usage can vary. In some cases, such as in discussing the weather, the sky refers to only the lower, more dense portions of the atmosphere.

During daylight, the sky appears to be blue because air scatters blue sunlight more than it scatters red. At night, the sky appears to be a mostly dark surface or region scattered with stars. During the day, the Sun can be seen in the sky unless obscured by clouds. In the night sky (and to some extent during the day) the moon, planets and stars are visible in the sky. Some of the natural phenomena seen in the sky are clouds, rainbows, and aurorae. Lightning and precipitation can also be seen in the sky during storms. Birds, insects, aircraft, and kites are often considered to fly in the sky. Due to human activities, smog during the day and light pollution during the night are often seen above large cities.

Mr. Blue Sky

"Mr. Blue Sky" is a song by British rock group Electric Light Orchestra (ELO), featured on the band's seventh studio album Out of the Blue (1977). Written and produced by frontman Jeff Lynne, the song forms the fourth and final track of the "Concerto for a Rainy Day" suite, on side three of the original double album. "Mr. Blue Sky" was the second single to be taken from Out of the Blue, peaking at number 6 in the UK Singles Chart and number 35 in the United States. The song was played as a wake-up call to astronaut Christopher Ferguson on Day 3 of STS-135, the final mission of Space Shuttle Atlantis.

Inspiration

In a BBC Radio interview, Lynne talked about writing "Mr. Blue Sky" after locking himself away in a Swiss chalet and attempting to write ELO's follow-up to A New World Record:

The song's arrangement has been called "Beatlesque", bearing similarities to Beatles songs "Martha My Dear" and "A Day in the Life".

Arrangement

The arrangement makes prominent use of a cowbell sound, although this is credited on the album, to percussionist Bev Bevan, as "fire extinguisher."

Mr. Blue

"Mr. Blue" is a popular song written by DeWayne Blackwell that was a hit for The Fleetwoods, reaching #1 on the Billboard Hot 100 in November 1959 and giving the group its second chart-topping hit of the year.

The Blues Brothers

The Blues Brothers, formally, variously The Blues Brothers' Show Band and Revue and The Blues Brothers' Rhythm and Blues Revue, are an American blues and rhythm and blues revivalist band founded in 1976 by comedy actors Dan Aykroyd and John Belushi as part of a musical sketch on Saturday Night Live. Belushi and Aykroyd, in character as lead vocalist "Joliet" Jake Blues (named after Joliet Prison) and harmonica player/backing vocalist Elwood Blues (named after the Elwood Ordnance Plant, which made TNT and grenades during World War II), fronted the band, which was composed of well-known and respected musicians. The Blues Brothers first appeared on Saturday Night Live on January 17, 1976. The band made its second appearance as the musical guest on the April 22, 1978 episode of Saturday Night Live. They made their third and final appearance on November 18, 1978.

The band began to take on a life beyond television, releasing an album, Briefcase Full of Blues, in 1978, and then having a Hollywood film, The Blues Brothers, created around its characters in 1980.
