LASS FROM LANCASHIRE HERE
Petite, blonde Ethel Formby, sister of the famous George, arrived in Melbourne from Sydney yesterday to fulfil an engagement with Tivoli Theatres, opening on October 11 in Folies Bergeres. Later she expects to tour Australia entertaining servicemen.
Had not Ethel followed in [George’s] footsteps, she could have made a name for herself by her own good looks and bright personality. She is little more than 5ft in height, with hazel eyes and fair complexion.
Taking up the ukulele, one of the many instruments in the Formby house, Ethel taught herself to play and sing, and it wasn’t long before she began to get engagements in music halls and revues, singing Lancashire dialect songs to banjo accompaniment.
In private life, Ethel is Mrs J. A. Gibson, wife of Battle of Britain pilot, Flt-Lt Gibson, DFC, a New Zealander serving with the RAF, whom she met and married in England a month after the war broke out.
