A Berkshire teaching assistant is riding high in the iTunes charts, but will never know of his success.
Jimmy Higham's cover of Stevie Wonder's Isn't She Lovely has outsold the likes of One Direction and Rihanna in the UK download chart.
A Twitter and Facebook campaign to get the song to number one has been endorsed by celebrities, rugby stars and radio DJs across the country.
But the PE teacher's surprise hit, which he recorded with work friend Jon Walmsley back in 2009, comes exactly a year after he died of cancer at the age of 26.
ITV News Correspondent Geraint Vincent reports:
Mr Higham had emailed the track over to university friends, who decided to release it as a single in November, just under a year on from his death shortly before Christmas 2011.
Since then, the song has attracted a growing audience, been played on national television and radio, and stormed the download Top 40.
All proceeds from the sales are benefiting a Bursary Fund established in his honour at Wellington College, the independent school he helped teach PE at in the village of Crowthorne.
