Does anyone actually enjoy the hideous heavy metal\hard rock (or whatever it is) "music" we are subjected to ?

I like that.

I'd also like to see themed days at home games as well, to add to the overall atmosphere. It's just as important to have a good show off-the-field, as on it, if we want to welcome families back.
For example:
Medieval day - Living up to our name and having jesters, juggling, knights, wizards, kids' run the gauntlet challenges, face painting, food etc. We could bring back that dragon mascot that was there on Saturday.
Beach party - Cocktails, smoothies, ice cream, inflatables, BBQ stalls, steel band etc. Obviously would have to take place in the summer months.

Those are just a couple of examples.

The whole "Cougarmania" that Keighley had going in the early stages of the Super League era was beneficial to the club on and off the picth, yet they were unlucky to not get the Super League position they probably merited.

I like the kids idea. Do the Junior RL kids in London still get free Season Tickets? Its a lot to give away but surely there's ways to work with this. For example, give tickets to each team. For example, give away 100 (just an example) tickets to kids from Greenwich Admirals one week, South London Storm the next and so on and so forth. Dads will have to pay, so there's some revenue. Get in entertainment, face painters, decent dancers, bouncy castles and mascot/fan interaction and maybe they'll return.

There was a band on Saturday competing with the England match.

Spot on

The band weren't competing with the England match. They were watching it....while playing. Idiots. As far as I can tell all sports club websites are sanitised and dull, Im not sure they make much difference tbh they're just a reference source for tickets and location etc.
