Here is Glenn Miller's Chattanooga Choo Choo in all its glory. This is the extended version from the film Sun Valley Serenade scored for Boy & Girl vocal with 4-piece backing group and it is four and a half minutes long! This version is a significant development from Miller's first version. In transcribing this chart we used not only the audio soundtrack from the film, but the film itself, in order to be able to see what the band were actually doing and playing. There are parts of the audio recording in which the band "disappears", particularly the Trombones behind the vocal chorus and the saxes behind the brass in the final shout chorus. By studying the players' fingering and slide movements on the film we have recreated what we think is the most authentic version of this chart you'll ever find. It has been a labour of love. The chart is also singable by a Boy / Girl combination, without the backing group - we've included an extra vocal part to cover this eventuality. Regarding Sax doubles, Alto 1 & Tenor 1 double Clarinets, Baritone doubles Alto. An instrumental only version is also available - see our Instrumental Glenn Miller section.
