"Feeling Good" (also known as "Feelin' Good") is a song written by English songwriters Anthony Newley and Leslie Bricusse for the musical The Roar of the Greasepaint – The Smell of the Crowd. The song was first performed on stage in 1964 by Cy Grant on the UK tour, and by Gilbert Price in the original Broadway cast in 1965. Nina Simone recorded the song for her 1965 album I Put a Spell on You and it became a standard. The song has also been covered by many artists, most notably by Muse, Michael Bublé and American jazz musician John Coltrane.
