Try this (if I understand it correctly)

SELECT
a.AnnoID, a.AnnoTitle, e.EventTitle as AnnoLink, date_format(a.AnnoDate,'%M %D %Y') as date
FROM tblANNOUNCE a LEFT (or INNER) JOIN mEVENTS e ON a.AnnoLink = e.EventID
ORDER BY AnnoDate DESC, AnnoLink, AnnoTitle

Choose LEFT or INNER depends on database structure.
