The New Orleans singer and pianist Dr John - best known for his songs Such a Night and Right Place, Wrong Time - has died at the age of 77 after suffering a heart attack.

The death of the six-time Grammy winner, whose real name was Malcolm John Rebennack, was announced on his official Twitter account.  

A statement read: "Towards the break of day June 6, iconic music legend Malcolm John Rebennack, Jr, known as Dr John, passed away of a heart attack.

"The family thanks all whom shared his unique musical journey & requests privacy at this time. Memorial arrangements will be announced in due course."

Dr John was world renowned for his melting pot sound that mixed blues, pop, jazz, boogie woogie and rock and roll.

He began performing as a teenager and was a top session musician before embarking on a solo career with his 1968 album Gris-Gris. He went on to release over 30 albums through the decades.

On screen Dr John appeared in Martin Scorsese's live music film about The Band, The Last Waltz, and HBO's New Orleans-set series Treme. He was also the inspiration for The Muppets character Dr Teeth.
