Probably not intended as such in 1949, in retrospect this film shows an interesting juncture between old time show biz and the imminent influence of television, which changed everything. The film captures some fascinating relics of an earlier time, such as Bert Lahr reprising a famous burlesque-type routine of his from the early '20s. Milton Berle excels in acting out all sorts of comedic styles and formats then in vogue or already seen as passe. Despite its chirpy title song, the film has a surprising toughness and unsentimentality for its era (witness the happily cruel "Men's Club" scene). Recommended for those into show biz history, and also a great way to see some genuinely funny stuff.
