As a fan of comedy teams, I have wanted to view this film for years. What a disappointment. Tommy Noonan and Peter Marshall have to be the most lackluster comedy team ever. Noonan had a successful career as a character actor ("A Star Is Born", "Bundle of Joy", "Gentlemen Prefer Blondes"), while Marshall's fame rests on his work as a TV game show host ("Hollywood Squares"). In this film, they do one marginal routine together, a pool game routine. It is marginally amusing. The rest of the film deals with con-man Marshall's attempts to get procrastinating composer Noonan to finish writing a song for a competition. The chemistry is really missing between these two guys. They are less a comedy team and more like two actors who happen to be paired in a film. There is a little slapstick, but it is very mild. There are musical numbers, but none are performed by Noonan and Marshall, both who have musical comedy backgrounds. Guest stars Ray Charles, Bobby Vee, and Roger Williams handle the musical end. I have been told that of the two Noonan and Marshall starring features, this is the better one. I have never seen "The Rookie", but it must really be terrible. "Swingin Along" is not unwatchable; it is merely mild, and a bit boring. As a side note, Alan Carney, of the defunct comedy team of Brown and Carney, has a small cameo in this film.
