Those of us on this side of the Pond may not recognize as "classical" all of the artists who have made "Classical Relief for Haiti," but the sincerity behind their efforts is beyond question.
Among the UK performers are cellist Julian Lloyd Webber, tenor Paul Potts (a reality-show sensation before Susan Boyle), the Priests (often featured in PBS pledge-time programming) and percussionist Evelyn Glennie, not to mention the Royal Philharmonic Orchestra.
This "We Are The World"-type fundraiser to benefit Haitian relief efforts is a performance of "The Prayer," a pop ballad recorded orginally by Andrea Bocelli and Celine Dion. Although the Web info on obtaining a copy of the recording says the CD version is for delivery to UK addresses only, I imagine that the downloadable version would be obtainable by anyone.
