The "James Bond Theme" is the main theme for "Dr. No", and has featured in all the Eon Productions Bond films in different versions. The theme has also featured on the gun barrel sequences at the beginning of the films. The original theme was written by Monty Norman, and was performed by John Barry and his orchestra in 1962. In the opening credits of "Dr. No", two other pieces were played: an untitled bongo interlude and a Calypso-flavored rendition of "Three Blind Mice", titled "Kingston Calypso". Due to this, "Dr. No" is the only film to have more than one opening theme. The "James Bond Theme" reached 13 in the UK Singles Chart, and remained in the charts for 13 weeks.
