There was a time, not long ago, when Baroque scores were treated as a folio of performance suggestions, not as the letter of the law. Performers felt free to add music or (more often) to take it away, and to do other things which were quite different from what the composer originally had in mind. Sir Thomas Beecham had no qualms about performing surgery on the music of George Frideric Handel, a composer he absolutely adored. No disrespect was intended. In fact, Beecham loved Handel so much, he wanted everyone else to love him too. That meant making him more palatable for modern tastes – bigger and leaner, at the same time.
It's been conventional wisdom for several generations that Solomon, great oratorio though it may be, contains a lot of deadwood; conductors have regularly cut some items and changed the order of others. (Even John Eliot Gardiner's excellent recording cuts about 30 minutes of music.) Leave it to Paul McCreesh to give us the complete score–and demonstrate that Handel's original structure makes plenty of sense and that every number is worthwhile.
