Yes, Harrison replaced Handy several years ago. Handy subs occasionally, though.
Went to Ronnie Scott's last Wednesday. Fun show with Ronnie Scott’s Club Quintet [(James Pearson (p), Alex Garnett (as/ts), Freddie Gravita (tpt), Sam Burgess (b), Chris Higginbottom (d)].
Their theme for the night was ‘1959 …The Year That Shaped Jazz’. So they played tunes like So What and Blue Rondo A La Turk, as well as a few originals in the same style.
Not familiar with any of the musicians, but the sax and piano player were standouts.
