Montel wanted to change the arrangement of the violins, but was persuaded by the KNUZ deejays to leave it as it was. It was nationally distributed as Montel #921 by Philadelphia's Jamie/Guyden Records after negotiations by producer Huey Meaux. Montel's prophecy was vindicated when "I'm Leaving It Up to You" reached No. 1 on the U.S. chart, where it remained for two weeks. Dale and Grace performed on tour with another Louisiana singing legend, Jay Chevalier. The song was No. 1 during the week that Kennedy was assassinated and also reached No. 1 on the Billboard Adult Contemporary chart. Houston appeared on Dick Clark's "American Bandstand". In autumn 1963, Houston and Broussard toured with his Caravan of Stars. The group, which also included Brian Hyland and Bobby Vee, was standing on a street corner on Main Street in Dallas waving at John F. Kennedy on that fateful day. Moments later, the presidential limousine turned right onto, ironically, Houston Street, then left onto Elm Street, where the president was killed and Governor John B. Connally was seriously wounded. The stars had gone back to their hotel rooms after waving to Kennedy and did not hear about the assassination until several hours later. In 1964, the duo released their debut album "I'm Leaving It Up to You and 11 Other Hit Songs". The popularity of The Beatles, combined with personal problems between the two performers, Broussard's homesickness, and a serious illness which landed Houston in the hospital, caused the duo to separate in 1965. Grace returned to singing with her brother. Dale Houston died on September 27, 2007 of heart failure at the Wesley Medical Center in Hattiesburg, Mississippi, age 67. At his funeral Troy Shondell gave a musical tribute, and interment was in Smyrna Cemetery in Collins, Mississippi. In 1995, Dale and Grace, having been reunited, were honored in Mississippi through resolutions of the Covington County Board of Supervisors and the Town of Seminary. In 2000, Houston received the 'Louisiana Living Legends Award' from the Public Broadcasting Service. Earlier, he was inducted into the Texas Music Hall of Fame and the Gulf Coast Music Hall of Fame, both in 1998. In 2007, newly elected Louisiana Secretary of State Jay Dardenne announced that Houston and Broussard, along with John Fred and the Playboys, were being named to the Delta Music Museum Hall of Fame.
