I just had a chat with Aidan and he is very open to this idea, even with the numbers that now seem interested. The only problem at the moment is arranging a date as his schedules are demand driven at the moment and he wouldn't be able to commit to a date a long way in advance. Later in the summer season he'll be able to plan more in advance and, as Ken said, move a brew day to a weekend. Maybe this would be a good time to catch up with him.
