Straatdeuntje ("Street Tune") was the Belgian entry in the Eurovision Song Contest 1957, performed in Dutch by Bobbejaan Schoepen.
At the close of voting, it had received 5 points, placing 8th in a field of 10.
The song is a moderately upbeat number, with Schoepen singing about a tune wandering up and down a street and being heard (and presumably performed) by all who hear it. The performance is memorable as well, as it featured a whistling solo. Schoepen is also rumoured not to have known which song he was to perform at the Contest until he arrived, only rehearsing his entry once before performance.
