Upon finding the female stranger, she tells Jo she wants to meet her ex-lover, Thompson - and reveals an epic story of the Adelphi Hotel's history, when Hollywood actors stayed there en route to UK and European destinations.
Back in the present, Jo is having trouble when Neil asks her to leave Liverpool and move to Japan with him, but she is more interested in hearing the strange woman's stories.
Finally, the stranger reveals how a dance for American soldiers in the Adelphi ballroom was interrupted by a destructive air-raid, and she tried to reach the roof to meet with Thompson.
As they embrace, Thompson arrives, and in the rain, the reunited couple finally dance on the roof, joined by the spirits of the show's characters.
The section starred Julie Atherton as Young Alice and Tom Oakley as Thompson, supported by an ensemble of final year students from Arts Ed school in London.
