I hope that this video is ok, it is slightly less than 1 minute long but near enough to 1 minute in length. The video is a bit shaky. I filmed this when I was in Dorset last week too. :)
To listen while using other apps, switch the player to Picture-in-Picture (PiP) during playback — it keeps playing in a small floating window (the screen stays on).
To listen with the screen fully off, in-browser playback stops by YouTube's design. Open the video in the YouTube app to keep listening where background playback is supported (e.g. with YouTube Premium).
