"A Beautiful Morning" is a song written by Felix Cavaliere and Eddie Brigati and recorded by the Rascals.
A modified version for this song was used by McDonald's during the late 80's "America's Morning Place" commercial series.
It was also featured at the end of a second-season episode of The Greatest American Hero, in which Ralph had to disarm a nuclear missile.
It was also used in the 1993 movie A Bronx Tale opening the racetrack scene, as well as on Arrow at the end of the eighteenth episode of the fifth season, titled "Disbanded".
The song's opening lines featured prominently in a 2002 TV commercial for the (since-recalled) pain reliever Vioxx, which opens with an idyllic clip of former Olympic champion figure skater Dorothy Hamill, skating on a pond amid bright sunshine.
