Ok....I should have been more clear.....they are not calling themselves Oldies 98 anymore, why keep the matching calls, especially if WCAU calls are available....of course what they are playing are oldies/classic hits/songs from yesteryear/songs you grew up with......etc........but since the 50's/60's were branded 'Oldies' first, people who were around when this happened tend to still associate the 50's/60's to the 'Oldies' brand.....I guess that is why the Oldies name is being dropped by stations who moved forward with their selected years of music.
(and.....yes, I know Oldies 99.9 in Allentown is the Hawk now and still retained their 'Oldies' call letters of WODE...another station who should change their calls)
