Jazz trumpeter Kenny Ball has died in hospital where he was being treated for pneumonia, his manager says.
Les Squires said the musician, who was in his early 80s, died in Basildon Hospital in Essex at 7.30am on Thursday.
He said: "He had been in and out of hospital recently but sadly this time he did not come out, but he was playing to the end."
Squires said Ball was survived by his partner and his son, Keith, who had joined his father on stage playing with his group The Jazzmen.
He said the musician had continued to perform, having left hospital to play a gig in Germany at the end of January, before being re-admitted.
Ball, who lived in Essex, found fame in the early 1960s with a string of trad jazz hits including Midnight In Moscow which got to number two in the charts on 1961.
The track, which was also a hit in the United States, sold more than one million copies around the world.
He became a well-known face on TV with his band featuring regularly on light entertainment shows.
They made numerous appearances on the Morecambe And Wise Show and went on to become the resident band on the popular BBC1 series Saturday Night At The Mill, which was broadcast from Birmingham's Pebble Mill studios.
He achieved his biggest hit with Midnight In Moscow - effectively his signature tune - but other top 10 hits in the early 1960s were March Of The Siamese Children, The Green Leaves Of Summer and Sukiyaki.
