Chart star Sam Smith says he is practising for his comeback gigs after vocal cord surgery by singing in the shower.

The Stay With Me singer cancelled a string of Australian dates last month after doctors discovered a hemorrhage on them and he was flown to the United States to see a specialist. He told t he BBC Radio 1 Breakfast Show with Nick Grimshaw that the problem was caused by ‘singing too hard for too long’.

He said t he last few weeks had been ‘horrendous’ after doctors banned him from speaking while he recovered, adding: ‘I haven't properly sung yet, I've just been singing in the shower and stuff. ‘I'm just trying to take it slow’.

The singer has had a meteoric rise in the last few years. Sales figures released last month show he had the best-selling album, single and most streamed track by a British artist in the US in 2014 when Stay With Me was played more than 147 million times.
