"Those who didn't come also missed an historic occasion. Grace Korrie (Hannah Shewan) who sang so delightfully is the great granddaughter of Miss Ellen Korrie and a great great granddaughter of The Musical Korries, who were a famous name in the Music Hall scene until 1930. They are depicted in a famous painting now in the Museum of London, "Popularity", by Walter Lambert which shows 231 of the most popular acts of the Edwardian Music Halls. The song she sang, "Dear Little Jammy Face" was written in 1908 for her great grandmother and first performed by her in 1909. A wonderful piece of Music Hall history."
