I've now received some confirmed information:
The Scouts Bonfire this year will be Saturday 3rd November
Bonfire starts: 7.00pm
Fireworks start: 7.30pm
Tickets £3.00 Adult, Child 5 to 15 years £1.50 available from Hollins of Marple or from Scout Leaders.
Usually it's cheaper to buy the tickets in advance and I think they will be £4 and £2.50 on the night (but this is not confirmed).
