It’s that time of year again – and the kids can’t wait!  The start of summer in the Flatiron District on the lawns of Mad Square Park means another summer of musical fun for both kids and adults, thanks to Madison Square Kids and the Madison Square Park Conservancy.  A morning stroll by the south end of Mad Square Park showed the strollers queued up and the rug-rat set and their parents out in force to take it all in on a sunny Thursday morning with Suz Slezak and her band.  The tykes up front were dancing and swaying to the tunes, and the adults looked happy, as well.  As in past years, the south end, great lawn and sand-gravel sections will feature a wide variety of musical acts for all ages.  The Madison Square Park Conservancy will combine musical presentations for both children and adults on the same days and the same stage in an effort to minimize setup time and maximize enjoyment.  Check out this quick Flatiron Hot! News Clip to get a sneak peak of the season’s first show!
