larry, bill harry is not a reliable source.i am sure that he would smoke screen any ill favorable news.
alan and his mom both died on the same day.
i think you need to find a non beatle related site to garner info.

May be right on Bill Harry, but he cites public sources.  So who knows.  Anyway, I do have many non-Beatle sources on this topic; but all of them though reflect contrarian stories -- with only one other siting the double death of Ma Caldwell and son Rory.  All of them loaded with mostly hearsay.

If find something official, I'll post it.  I've actually been searching for additional credible material on this one for nearly two years now, but to no avail.  Rory has surviving siblings (sister (Iris), but no one in the Caldwell clan is talking.

maybe police records.
hey end-of-alan,are public records available for public veiwing over there?
that could hold some answers.
only 2 years?i have looked for 10 at least.
