She was awarded the OBE (Officer of the Order of the British Empire) in the 1990 Queen's Birthday Honours List for her services to the Not Forgotten Association.
She participated in BBC Television's A Song for Europe contest, the UK qualifying heat for the Eurovision Song Contest. Her entry, "I Will Light a Candle" was placed fourth. Shelton made another attempt at Eurovision in 1963 with "My Continental Love" - and came fourth again.
In 1949, Shelton began to make headway stateside, scoring a pair of hits with "Be Mine" and "Galway Bay," which resulted in her inaugural U.S. tour two years later (all the while continuing to entertain the troops).
On occasion in her career, she was accompanied by her sister, Jo Shelton, also an accomplished and popular singer.
