Question: What country was the artist born in that Bundrick worked with on Rough Mix in 1977? Passage:Bundrick first worked with Pete Townshend in 1977 when he performed on Rough Mix, Townshend's solo collaboration with Ronnie Lane, former bass player for Small Faces and Faces. He was invited to play on the Who's album Who Are You (1978), but broke his arm falling out of a taxi at the studio door and was unable to participate in recording sessions. Bundrick toured with The Who from 1979 to 1981 along with drummer Kenney Jones and played on their album Face Dances (1981), then briefly parted with the band during the recording of It's Hard (1982) and the subsequent tour. Bundrick later rejoined the band performing with them at Live Aid in 1985 and played live with them until 2012.

Question: Who was older when Heitler obtained his doctorate, Arnold Sommerfeld or Karl Herzfeld? Passage:In 1922, Heitler began his study of physics at the Karlsruhe Technische Hochschule, in 1923 at the Humboldt University of Berlin, and in 1924 at the Ludwig Maximilian University of Munich (LMU), where he studied under both Arnold Sommerfeld and Karl Herzfeld. The latter was his thesis advisor when he obtained his doctorate in 1926; Herzfeld taught courses in theoretical physics and one in physical chemistry, and in Sommerfeld's absence often took over his classes. From 1926 to 1927, he was a Rockefeller Foundation Fellow for postgraduate research with Niels Bohr at the Institute for Theoretical Physics at the University of Copenhagen and with Erwin Schrödinger at the University of Zurich. He then became an assistant to Max Born at the Institute for Theoretical Physics at the University of Göttingen. Heitler completed his Habilitation, under Born, in 1929, and then remained as a Privatdozent until 1933. In that year, he was let go by the university because he was Jewish.

Question: Which record label that were involved in the recording rights dispute was first established? Passage:In a highly unusual situation, two LP albums of the score were released. The recording rights had been granted to RCA Victor, which had invested in the show, but Merman was under contract to Decca Records, which refused to allow her to record the original cast album. Decca issued a 10-inch LP featuring Merman singing some of her songs, accompanied by arranger-conductor Gordon Jenkins and His Orchestra and Chorus, with vocalizing by Dick Haymes (who joined Merman in the show's biggest hit, "You're Just in Love", their single reaching Billboard magazine's number 30 for a week) and Eileen Wilson (who sang "It's a Lovely Day Today" with Haymes). RCA Victor went ahead with the original cast album replacing Merman with Dinah Shore. Merman was called back into the Decca studios to record additional songs from the show, and the label quickly re-released the album as a 12-inch LP under the title Ethel Merman: 12 Songs from Call Me Madam. The Victor album sold reasonably well, attaining the sixth spot on the Billboard popular album charts, but the LP was out of print from 1956 until RCA Red Seal reissued it briefly in 1977. Peaking at number two on Billboards popular album charts, Merman's Decca recording, which would appear on MCA Records beginning in 1973, stayed steadily in print until the end of the LP era. Merman's Madam album currently is available on a Decca Broadway CD, which also features Merman singing four Cole Porter tunes from the stage score of Panama Hattie (1940).
