The Stay With Me hitmaker underwent an operation on his vocal cords in May (15) after he developed a haemorrhage, forcing him to cancel a string of tour dates.
The singer has laid low since the surgery, until he got up on stage for a mass sing and dance number with Nile Rodgers and Chic in London in June (15), and he has now proved his singing voice has returned.
Smith posted a video on Instagram.com of him performing a soulful version of Presley's 1961 classic Can't Help Falling in Love during what appeared to be a soundcheck for a concert. In the caption, he simply wrote, "I'm back".
Smith is expected to return to the stage for the Forest Live outdoor concert in Suffolk, England on Sunday (05Jul15).
