"High Hopes" is a popular song first popularized by Frank Sinatra, with music written by Jimmy Van Heusen and lyrics by Sammy Cahn. It was introduced in the 1959 film A Hole in the Head, nominated for a Grammy and won an Oscar for Best Original Song at the 32nd Academy Awards.
The song describes a few impossible scenarios, where animals do seemingly impossible acts. For example, an ant moves an entire rubber tree by itself, while a ram single-handedly knocks down a dam. The lyrics refer to a "billion kilowatt dam", which would be a terawatt dam. As a comparison, China's Three Gorges Dam will only produce 2% of that amount (22.5 GW) when all generators are in place.
"High Hopes" was recorded by Frank Sinatra in 1959 in a hit version, featuring a children's choir, which was included in a 1961 Sinatra album, All the Way. The tune reached #30 on the Billboard Hot 100. Frank Sinatra recorded a version of the tune with different lyrics which was used as the theme song for the 1960 Presidential Campaign of John Kennedy.
