Elegy - after all these years, Colosseum's recording of James Litherland's song still sends shivers down the backbone. And I experience the same thing during the final hour of a jam-packed charity tribute to Dick Heckstall-Smith, who died last December. Shy but in good voice, Litherland comes on to sing Elegy with Tony Reeves on bass (replacing the usual Mark Clarke) to recreate the original lineup of the band, except for Heckstall-Smith himself, whose saxes stand on a podium in silent tribute, while Barbara Thompson, drummer Jon Hiseman's wife, plays the parts.

Earlier, there had been short sets from the saxophonist's old colleagues in Big Chief and DHSS (including pianist Jonathan Gee) plus Mick Taylor, John Etheridge, lyricist Pete Brown and a trio set by Jack Bruce with Gary Moore and Gary Husband.

Hiseman and Heckstall-Smith dreamed up the idea of Colosseum as a band with "no drug addicts or time-wasters" while they were part of the tumultuous jazz-blues scene of 1960s London. Thirty-six years on, Colosseum still rock: combining the raw emotion of an electric blues band with jazz chops. Hiseman treats the audience to a flamboyant solo, with thundering drums and circus-like stick tricks.

The rest of the band - Clarke, organist Dave Greenslade, guitarist Clem Clempson and singer Chris Farlowe - return for Valentyne Suite, Walking in the Park and Stormy Monday, which gives singer Chris Farlowe license to thrill, with screeching high notes, raw blues hollering, but occasionally pulling back to a fragile, almost feminine jazziness. And it's good to be reminded of what a monstrously fine guitarist Clempson is.

Heckstall-Smith added a musical intelligence to the British scene at the point where 1960s pop, blues and jazz collided to make rock. It was great to see this packed audience pay tribute to him.
