Patrick Aspbury, of Chelmsford, was one of three cathedral singers who formed The Choirboys in 2005 and enjoyed a blaze of fame on Decca Records until their voices broke.
Patrick, 23, grew up into a promising young composer.
He was struck last week by a train at Chelmsford station.
There will be an inquest.
