I couldn't quite picture it, so I walked all the way along there beyond the House of Wang to the Edge of the Known World. Frankly, it would have been much easier if you had just pictured it and posted it for me.
Let's face it - it's not a bandstand. I don't know what it's supposed to be really. It might be a rain shelter, except that the seats are all on the outside. And they are facing the wrong way to be of use to spectators. And it's too small for any kind of entertainment, apart perhaps from a very small and intimate puppet show. (Punch and Judy?) It's just a folly really, an architect's doodle. If you have a look at the structure underneath, it looks as though it is starting to rust pretty badly as well. Don't suppose the salt water helps.
The 'cake stand' benefits from a more central location, is an ideal size, ready-made stage, grassy park, prom and beach for spectators.
You wouldn't like a skateboard facility at your end instead, would you?
