Arnold comes from three generations of Soho entertainers. The musical is inspired by his 2006 solo album of the same name and tells the stories of the real people behind London’s most colourful area, drawing on his own family’s experiences. His mother, former Windmill showgirl Polly Perkins, will feature in Thursday’s showcase along with West End musical leading lady Kelly Price and cabaret legend Peter Straker. Thursday’s late-night showcase, starting at 11pm, is by invitation only. For further information, visit the show website at www.secretsofsoho.com.
