I found this piece thoroughly charming! I picked it up on eBay in Super-8 with no idea of what it might be, and was agreeably surprised to find a Fleischer sing-along 'Car-Tune'. Those demanding the justly celebrated Fleischer pyrotechnics should pass on this title, since the Car-Tunes weren't full cartoons but an animated answer to the magic lantern slide theater sing-along. As such they're very enjoyable, especially if you do sing along. There was originally special sheet music that synchronized with the film, adding a few sound effects as well.
The (admittedly simple) animations as well as the time-tested lyrics of 1902's classic hit 'In the Good Old Summertime' provide a nostalgic evocation of old-fashioned summer fun that should bring a smile to most faces. So if you come upon this little film, go ahead-- hold hands with your 'Tootsey Wootsey' and join in!
