''Bye Bye Birdie,'' the touring revival of the 1960 musical starring Tommy Tune, will replace ''House of Flowers'' in the Morris A. Mechanic Theatre-Lyric Opera House 1991-92 schedule.
''House of Flowers,'' with Patti LaBelle in the lead role, was to have played the Lyric Feb. 11 through March 8. The producers have postponed the tour, according to Hope Quackenbush, managing director of the Baltimore Center for the Performing Arts, which oversees the Mechanic.
In ''Bye Bye Birdie,'' Tune plays the manager of rock singer Conrad Birdie, who, as a publicity stunt, will kiss a young lady on the "Ed Sullivan Show."
