Just heard on the grapevine that on Friday after performing the last gig of their residency at the Shaw Theatre, Harry Connick Jnr and Branford Marsalis later arrived with their crew a small club, the Octave in Endell Street, Covent Garden for a late supper. After listening to some local musicians finishing their sets (Estelle Kokot and Emma Blake), Marsalis and Connick then got up on stage and performed for the club audience.
