Rolling Stock (Reprise) / Girls' Rolling Stock is an upbeat number in act 2 of Starlight Express, in which coachesAshley and Buffy (and originally Belle ) pick up Dinah's confidence, persuading her to fight back and win back her man, Greaseball. It's a short, punchy number that allows the coaches other than Pearl to have a moment in the Spotlight.
Productions
Rolling Stock (Reprise) was part of the original score, with the vocals heavily led by Belle and Dinah, with Ashley and Buffy singing the harmonies while dancing. Once Belle was removed from the show, Buffy and Ashley were required to sing more extensively. The song was also re-choreographed at the time.
The same number is called "Girls' Rolling Stock" in the German production. It was cut from the 2004 UK Tour, but replaced in 2012 UK Tour, again re-choreographed.
