In 1925, Andy Woolfries starts a show called ‘The Music Shop’ which has continued ever since (now heard on WOI-FM, which turned on the heaters on July 1, 1949).
Rock band Chicago Transit Authority releases its first (eponymous) album, which will rise to US#17.
Soon the band changes its name to Chicago and becomes one of the most successful US pop and rock groups.
Chicago’s next ten albums land in the US top-10; five in a row make US#1 (Chicago V to Chicago IX). Songs from those albums include Saturday in the Park (1972 US#3), Just You ‘n’ Me (1973 US#4), and Old Days (1975 US#5)
It’s from second album One of the Boys(US#9,UK#11), released on June 17, which receives some heavy criticism. It includes single Hot n Cold(US#3), and may or may undo some of the damage done by (included) Nov 2007 single Ur So Gay (Perry is heterosexual). Lyrics
Perry’s next two albums are both international top-5 hits. Third album Teenage Dream, released Aug 24, 2010, tries out a different audience. It’s the second album in history to generate five US#1 hits (after Michael Jackson’s 1987 Bad), despite more critical bile. It wins Juno Award for International Album of the Year in 2011, and seven Grammy nominations.
