I AM sorry to have to correct an error in Robert Hale's preview of the forthcoming ESO concert, but ... the performance by the celebrated pianist Emmanual Ax is not his Malvern debut. That took place on March 12, 1981 when he and Richard Stoltzman gave an extremely successful recital for the Malvern Concert Club, further details of which may be found in the centenary history of the Concert Club to be published in July.

MICHAEL MESSENGER, St Peter's Road, Malvern.
