In a previous East Side Kids movie called 'Neath Brooklyn Bridge, Noah Beery Jr. played a former member of the gang. Here his father, Noah Beery Sr., plays an uncle (so to speak) of Muggs from Texas with his grown daughter in tow. In seems Muggs' mom had a late husband who exaggerated about how many children they had when he wrote to his friend. So guess who becomes the other 6 siblings of Muggs including one sister? Anyway, this was more of a comedy than drama though there's still somewhat of a thrilling finish of the latter. So on that note, Clancy Street Boys was a very enjoyable East Side Kids adventure. P.S. Since I always like to cite when a player of my favorite movie-It's a Wonderful Life-is in something else I review, here it's J. Farrell MacDonald as a police officer named Flanagan.
