Lawrence Welk, Soundtrack: The Lawrence Welk Show. The accordion maestro provided nearly two decades of squeaky-clean music and family entertainment on TV every Saturday night between 1955 and 1971 on prime-time, and for another 11 years in syndication. His trademarks included his "A uh-one, a uh-two" intro and a perpetual bubble machine. awardsbiographyboardsmessagenewsphotos in Celebritieswith celebritiesimdb.urllawrencewelk
