Here is a letter published in today's Guardian, spearheaded by the Chetham's-educated pianists Paul Lewis, Tim Horton and Ian Pace and signed by hundreds of musicians and others (including some critics). It calls for "a full independent inquiry into the alleged sexual and psychological abuse by Chetham's staff since the establishment of the institution as a music school in 1969. Such an inquiry would ideally extend to other institutions as well, some of which have also been the subject of allegations of abuse."
A full list of signatories can be found here, on Ian Pace's website.
[Update] Those concerned by the sexing up of young female musicians throughout the industry - something we've written about extensively in the past here - might also be interested to read this piece from Ian's site: http://ianpace.wordpress.com/2013/02/11/chris-lings-views-on-sexing-up-classical-music/
