Let’s take a moment, on this sunny Monday morning, to pay tribute to Mickey Rooney, whose death yesterday at the age of 93 ended one of the longest careers in show business. A former child star, the diminutive Rooney began making movies in the 1920s, found fame in the 30s as Andy Hardy and as a frequent musical sidekick to fellow teen Judy Garland, and continued to work consistently in television, stage and film (he could be spotted in “The Muppets” in 2011, and at the times of his death was shooting a version of “Dr. Jekyll and Mr. Hyde”). His performing life, which began as a toddler singing in his parents’ vaudeville act (his father was a comedian; his mother a dancer), brought him four Oscar nominations, five Emmy nominations (including a win, for the 1981 TV movie “Bill”), a Tony nomination (for Broadway’s “Sugar Babies” in 1980), and the love of many generations. Here’s a charming moment from “The Judy Garland Show” from the early 1960s, where two old friends (they starred in four musicals together) got together for one more song; here’s hoping they’re happily dancing together again today, somewhere.
