Hi!
Thanks to Martin Renshaw's assistance the 1856 Sprague instrument at Hammerwood Park is now in performing condition. Foot blown, it represents a challenge to modern players.
It can be heard performed by John Cooper of Ipswitch on http://www.youtube.com/watch?v=FFErBGuB26o with Byrd, Buxtehude and Brahms.
Best wishes
