Jurgen, not sure which years you were listening to BFBS, but I listened in the early 70's and Richard Astbury (Asters) was the main presenter. I think he was known as the housewives favourite since he had a good flirty rapport with young soldier's wives.
I know he had quite a strong German following as well, especially with Germans learning English.
He played several comedy disks (wow that sound old) such as "drinking mans diet" and "Belfast Belfast". He might have presented the Charts as well. Gosh do you remember how bad the German Hit Parade was (or was this just me?).
I'm sure Asters wouldn't mind an email if you need this information, check out his Website
