"I know this. Found out some years ago, thanks to this site :-)! It's "WebMusic - Song Favourites", a copyright-free song... Available here if you are not geoblocked: https://open.spotify.com/album/0o7KAX9Bcv8akBL2khqDBS?highlight=spotify:track:0RlL4EyQuLsjlF7dT4u89H. I don't remember the timing but just listen to the whole track. If you can't listen to it, here's my own personal copy (already cut to the right timing): https://vocaroo.com/gt4VkjIJMbH. And a precision for those who have iMovie on their Mac's: the track is integrated to the software and its called "Collins Avenue" in the sample database ;-)... Hope you got everything you need!"
