Originally from Ireland, Fitzmaurice came up under Trevor Horn and Julian Mendelsohn. The man who played an important role in Smith's solo success is a dyed-in-the-wool studio professional, with an impressive pedigree going back to the late 1980s.

The two songs and the album all topped the UK charts, while 'Stay With Me' was number five on the Billboard singles chart in the US at the time of writing. Yet in the first half of 2014 Smith scored two big solo hits, 'Money On My Mind' and 'Stay With Me', while In The Lonely Hour charted high in many different countries around the world.

The first time I recorded him, laying down his vocals on 'Money On My Mind', it was immediately obvious what an amazing talent he is.

He sings completely effortlessly and natural. He is the best singer I have worked with since I worked those legends. 'I've been lucky enough to work with some of the world's greatest singers, like Rod Stewart, Tina Turner, Cher and Seal,” says Steve Fitzmaurice, 'and Sam is easily in the same league. When an unknown act such as Sam Smith hits the big time, there's often an experienced producer behind the scenes - like Steve Fitzmaurice.
