WAY back in 1976, I flew to New Orleans to cover the world heavyweight championship fight between Muhammad Ali and Leon Spinks.
Down old Bourbon Street in the French quarter of The Big Easy I took in the sights and sounds of the world's most famous jazz city.
In one bar I found Clarence Frogman Henry singing 'I Don't Know Why I Love You But I Do', a song which had found its way to the top of the British hit parade in the 1960s.
And in another I discovered these three chirruping ladies belting out the blues in an inimitable fashion. What fascinated me, apart from their music, was their extremely animated mouths, which performed unimaginable contortions as they hit the high notes.
Forty-three years on, here am I trying to capture something of their mesmerising magic in a simple sketch. It's called Jazz Trio, New Orleans.
