ROSEMARY CLOONEY, one of the most popular vocal artists of the 1950s, is winning a new generation of fans and enjoying a revitalized career in both the popular and jazz fields. In 1951, bandleader and conductor Mitch Miller persuaded her to record the novelty song “Come On-A My House,” which catapulted the young singer to stardom. The next few years saw an incredible whirlwind of professional activity: concerts, movies (including the classic White Christmas in 1954), recordings, and television. Her autobiography, This For Remembrance, was dramatized for television. In 1995, she was nominated for an Emmy Award for “Outstanding Guest Actress in a Drama Series” for her role on NBC’s top-rated “ER.” Her 20th album for Concord Jazz, Dedicated to Nelson, received a 1996 Grammy nomination in the “Traditional Pop Vocal Performance” category. That was followed in 1998 by a Grammy nomination for Rosemary Clooney’s White Christmas. Clooney has appeared often at the Hollywood Bowl, both with the Los Angeles Philharmonic and on the Jazz at the Bowl series. Her most recent Bowl performance was in 1998.
