Jim clark the racing driver, Colin Chapman of Lotus both owned Piper Comanches in the 60's, both the single and twin versions.
Christopher Reeve used to come down to the Tiger Club in his slightly tatty Triumph TR6, wearing very casual clothes. He used to fly the Tiger Moths and Stampes. Always ammused me that he would sit in the club room, totally incognito -- most of the people did not know who he was.
Later on he starred in a documentary film about the Tiger Club ---- does any one have a copy ?
