Guitarist Jo Caleb and his vocalist wife Lisa run a tight Monday-night ship at this busy Chiswick inn.

Normally a comedy venue for the likes of Al "the pub jazz fan" Murray, its spacious function-room hosts the kind of jam-session where young bucks locked horns in the days before jazz education became a mass-production line.

It was good to see the old protocols observed last night. The opening set was for professionals. Sitters-in, having lodged the necessary request, appeared only after the interval. ("I can usually tell if they can't play," Lisa confided.)

Caleb developed his solos carefully on a seven-string Lucca guitar, assisted by drummer Troy Miller, double-bassist Larry Bartley and a worthy guest star, flautist Gareth Lockrane.

A product of the National Youth Jazz Orchestra, the tall Lockrane has matured into a world-class player. On any other front-line instrument he would be universally recognised as such, but too many listeners can't get past the flute's fragile sound. They don't hear the strength and fluency of his ideas.

Miles Davis was their muse as the quartet re-examined Solar, Blue in Green and a medium-tempo blues. Lisa joined them for a brisker version of My Shining Hour, with Miller on brushes and Lockrane gliding through the changes on his U-shaped bass flute.

Nothing startling happened when younger faces finally took over on bass, drums, guitar and trombone, but one never knows. There'll certainly be fireworks when Soweto Kinch joins the fun next year.
