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.
