Question: Question: Was Tony Sheridan on any other songs with the Beatles? Passage:Ain't She Sweet was an American album featuring four tracks recorded in Hamburg in 1961 by The Beatles featuring Tony Sheridan (except for the title song with vocal by John Lennon) and cover versions of Beatles and British Invasion-era songs recorded by the Swallows. As Atlantic Records only had rights to four Sheridan/Beatle recordings recorded by Polydor Records, they filled the rest of the album with Beatle and British Invasion cover songs. When this material was released by Atco Records, there were mono (catalogue number 33-169) and stereo (SD 33-169) editions. Atco also added additional drum overdubs to the four Sheridan cuts on top of the original drum tracks. American drummer Bernard Purdie claims to have performed overdubs of unspecified Beatles records, which would most likely have been for Ain't She Sweet, but this has never been officially confirmed.

Question: Question: What is the height of the peak of the mountain where the Aspen Mountain ski resort was established? Passage:The Company was founded in 1946 by Friedl Pfeifer, an Austrian ski instructor and racing champion, Walter Paepcke, a successful Chicago industrialist, Judge William E. Doyle, James J. Johnston, and H. F. Klock. Paepcke also founded cultural institutions in the city, such as the Aspen Institute and the Aspen Music Festival. The Aspen Skiing Company established the Aspen Mountain ski resort on Aspen Mountain above the town of Aspen, Colorado. The first chair lift, Lift-1, opened on December 14, 1946, and was the world's longest chairlift at the time. In 1950, the company hosted the FIS World Alpine Championships, the first international skiing competition in the United States. In the following decades, the company opened Buttermilk in 1958 and the Snowmass (originally the Snowmass-at-Aspen Ski Area) in 1967. In 1993 the company assumed ownership and operation of Aspen Highlands, which was founded in 1958 by Colorado Ski Hall of Famer: Whip Jones. Previously, Jones successfully sued Aspen Skiing before the Supreme Court for antitrust violations in Aspen Skiing Co. v. Aspen Highlands Skiing Corp.

Question: Question: Which continent where the 420 class racing vessels are popular currently has the larger population? Passage:Yachting has a long and prolific history in the area. New Silver Anchorage was dredged from Wild Harbor in the 1920s to shelter Beetle Cat boats which had become popular among the Cape Cod elite. Prior to the Second World War organized sailing flourished out of Wild Harbor, however U-Boat hysteria during the war led to dwindling popularity. On August 30, 1953, the Wild Harbor Yacht Club was formed on Wickertree Road to primarily serve New Silver and its constituent communities. The Club was incorporated by the United States Sailing Association the following year. A Widgeon fleet was organized in 1979 which brought the sport of sailing back into regional popularity. The club clinched the Southern Massachusetts Beetle Cat championship in 1981, 1982, 1984, 1985, 1986, 1987, and 1989. In 1990 the club focused its junior sailing on the new 420 class racing vessels which were already popular in Europe and Australia. Wild Harbor is a regional powerhouse and dominates the north shore of Buzzards Bay and competes competitively in the Southern Massachusetts Sailing Grand Prix. Wild Harbor has produced three collegiate all-Americans and a member of the 2000 US International 470 team.

Answer:
In 1990 the club focused its junior sailing on the new 420 class racing vessels which were already popular in Europe and Australia
