Starlight Express (song)

"Starlight Express" is the 'showstopper' number from the musical "Starlight Express". In the show, it is performed by Rusty, the show's protagonist. Before the song, he has been told by the old steam engine Poppa of a magical locomotive, named the Starlight Express, who will aid him in need.
The song has been rewritten in many languages, but has always kept the same title, apart from when the production opened in Mexico, when both the show and the song were renamed "Expreso Astral".
Music and lyrics.
The music was written by Andrew Lloyd Webber, in the key of E flat major, modulating to E major at the instrumental. In the Broadway production, Greg Mowry sings the song in the key of G major and modulates to Ab. The lyrics were written by Richard Stilgoe.
Before the song starts, Poppa and Rusty have the following (sung) conversation;
The song begins, and the introduction is the main theme played on a harmonica, and this is repeated for the instrumental.
Revision.
The song has undergone some revision since the show was premiered in London. The first draft started with the line
However, the verses were rewritten when the show opened on Broadway, in Germany, Japan and Australia. To fit the new tune, new words were written, starting with:
A new middle eight was added as well.
When the show was revised in London, both drafts were fused together, with the verses from London and the middle eight from later productions. This draft has become the most popular and well-used.
The original London tune has been revived for the revised Bochum production.
Thematic value.
The tune to the chorus is used throughout the show, for instance, when Rusty first hears of the Starlight Express; during the 'Starlight Sequence'; and when Rusty triumphs over his challengers (see main article). It is probably meant to show a point where there is a strong development in Rusty's character.
Starlight Express Introduction.
The Starlight Express Introduction was performed on Broadway and in London by Poppa and Belle. In later revisions, it is performed only by Poppa and has been shortened significantly. The number uses the first verse and chorus tunes from the London Production, and is used for the moment when Rusty first hears of the Starlight Express. In the first Bochum version this part was sung by Poppa and Control.
