I went on a touring holiday to Jordan in the early 90s for a week over Christmas (Aqaba, Wadi Rum, Petra etc). John Challis was also on the holiday. On the last day we went to the Roman City of Jerash, which is just north of Amman. There is a large outdoor theatre which dates from Roman times and the acoustics are such that someone speaking on the stage can easily be heard everywhere. The tour guide asked for someone to demonstrate and John volunteered and did speak.

I should say he was completely different to Boycie and did not have the moustache.
