Surprisingly few pictures exist of pre-war and immediate post-war entertainers on stage in Jersey, probably because publicity pictures tended to be taken in outdoor locations and, long before the age of the smart phone, those attending performances did not have cameras with them, particularly not equipped with a flash. So this picture, taken at the Plaza ballroom in the late 1940s, of Jack Dale and his band, is particularly welcome. Jack Dale was a clarinet/saxophone player from Birmingham who played as a member of Benny Loban and his Music Weavers on the 1930 recording of L'imagine

Sisters-in-law Valerie (1936, Willesden, London, England) and Elaine Murtagh (1940, County Cork, Eire) originally performed as the Avon Sisters. After being discovered singing at the 1958 BBC Radio Exhibition, they signed to UK Columbia Records where they recorded with producer Norrie Paramor. Their debut was Which Witch Doctor‚ with the Mudlarks, and their debut solo release was a cover version of Jerri O - both songs failed to chart. They added Ray Adams, who was born in Jersey in 1938, whom they spotted singing with Nat Gonella's Band, and then changed their name to the Avons. Their first single under the new name, a cover version of Paul Evans' Seven Little Girls Sitting In The Back Seat‚ in 1959, gave them their only UK Top 20 chart entry.
