Another composer to rework material from "Tristan" was Emmanuel Chabrier in his humorous "Souvenirs de Munich – quadrilles on themes from Wagner's Tristan und Isolde". These were augmented and orchestrated by Markus Lehmann in 1988. Leopold Stokowski made a series of purely orchestral "Symphonic Syntheses" of Wagner's operas during his time as conductor of the Philadelphia Orchestra, bringing to concert audiences of the 1920s and '30s music they might not otherwise have heard. He made a 'long version' of music from "Tristan and Isolde" which consisted mainly of the act 1 prelude, the from act 2 and the from act 3. A shorter version of music from the 2nd and 3rd acts was called "Love Music from "Tristan and Isolde"". He made recordings of both versions on 78s and again on LP.
