I don't think Sweeps would be too much of a problem as any event at the Coach House would be a one day thing just involving those who had a connection, not a rival festival. Sweeps could also be an advantage as it means those coming from afar could make a w/e of it.
Hartley and Wadard Morris Men, who were both based there at different periods, do there own thing on Mayday morning and are not involved with Sweeps so could be around in the afternoon/evening.
I have been in contact with Blossom and although its early days yet it should well be possible for Skinners Rats to get to both events.
In view of the fact that several prominent personalities from the early days are sadly no longer with us I am mindful that this could be the last opportunity for a grand reunion.
I don't even know if the Coach House would be available but if there is enough interest I will start the ball rolling in respect of enquiries/liaison/organiation.
