Dusty Springfield
Saturday, August 20, 2022 at 7:45 AM

Having been waiting, along with Pat Rhodes, for more information for a few days now, we are very saddened to have had confirmation from his solicitor that Dusty’s brother, Tom, passed away at home in London on July 27th. Being a very private person, the news somehow went under the radar and has only now come to light. Tom, who changed his name by deed poll in 1977 from Dionysius Patrick O’Brien, was 88 years old. Making his name in The Springfields, the group he formed in 1960 with Tim Feild, his sister Mary and later Mike Hurst, they went on to become the number 1 group in the UK before disbanding in the Autumn of 1963. Having written many hits and album tracks for the Springfields, following the break up he became one of the prominent songwriters of the 1960’s providing hits for Dusty, The Seekers, Frank Ifield, Anita Harris, Jose Feliciano and many others. Bless you Tom, rest in peace and thank you for the magic of your music.
