Oh what a shock we have just found this thread.
We hope as Ray's comment above that Brian Rogers has been informed, unfortunately I cannot find Brian's email.

Lionel was indeed a quiet person, although when he smiled the room seemed to light up. We had the pleasure of staying with him whilst visiting the Bag O Shoddy many years ago. However during the recent years we always used to meet up with him, Arthur & Brian at the Big Sing in Chippenham. He was also a regular in the audience on the front row at our Folk Club on Friday & Saturday Nights.

We and the folk world will miss him,
Pearl & The Admiral
