The track list includes the 'Overture.' Even though it could not be verified, the fact that the Broadway cast album has this track indicates it probably is on the London cast, as well.
The title role of ANNIE in London was created by Andrea McArdle, reprising her Broadway role. Alternate Annies were: Ann-Marie Gwatkin, Christine Hyland, Anne O'Rourke, Jacinta Whyte, Ruth Beesley, and Rosa Michelle who was the first to replace Andrea McArdle. Ann-Marie Gwatkin performs the role on the Original London Cast album and Rosa Michelle recorded a 45 single of two songs which will be found in the excerpts section.
