For those who have read Sverre's recollections it might be worth mentioning that Marilyn was born 1926 and visited the UK once in 1956 at the age of 30 on her honeymoon.
PRK: You’re kidding me! You dated Marilyn Monroe! You were a boy! Sverre: Yes, I was an old fourteen and a half, she just 35. Quote Sverre i was born october '46.
Peter-R. Koenig is a brilliant publicist in finding Sverre ,someone who undoubtedly knew David as a boy...pity about Sverre's over egged imagination ;D he would have been nine at the time Marilyn Monroe visited the uk.
