Five days into the Edinburgh Jazz Festival and even the most seasoned campaigner can begin to lag.

Thank the Lord, then, for Ken Mathieson's Classic Jazz Orchestra and its Beiderbecke-heavy Tuesday evening programme. There is nothing like a blast of Bix to buoy this girl's flagging spirits – and the CJO obliged, in style, serving up so many uplifting and jubilant 1920s hits that it was almost impossible to resist the urge to rouge one's knees, bob one's hair and embark on a dance marathon with gay abandon (if not a gay friend).

The Beiderbecke repertoire is packed with gems which Mathieson has dusted off and lovingly arranged for his eight-piece band, and it's always a delight to hear them being played with so much panache and enthusiasm, especially by such terrific younger players as trombonist Phil O'Malley and tenor saxophonist Konrad Wiszniewski.

One of the particular joys of the CJO's interpretations of Bix music is the way in which the cornettist's unforgettable and often exquisite solos have been retained and arranged for the entire outfit to play, often in unison. On Tuesday a highlight was the famous I'm Comin' Virginia solo which trumpeter Billy Hunter began on his own before being joined by le tout ensemble.

Other stand-outs in this Bix bonanza were From Monday On, Ostrich Walk and There Ain't No Sweet Man That's Worth the Salt of My Tears which featured a dazzling solo from Wiszniewski who was also memorably showcased on Buddy Tate's Idlin'– from the non-Beiderbecke part of the programme.
