With Derryn Hinch turning 60 today surely 3AW have a group of presenters that hold some sort of record for the number of hours worked on air. Without including the morning 'boys', just the combined age of the following is amazing - 311 years young. Ernie Sigley 65, Phil Brady nudging 65, Bruce Mansfield clocking up the big 60 in April, Hinch just gone 60 and Keith Mcgowan heading towards 61.
