To best of my recollection Bob and Ray started as local boys on local radio - Lowell, Mass, Radio WLLH and when they "caught on" went to the big time at Boston Radio WHDH.
But I've been wrong three times before!
Ann Goulding, Ray's younger sister, went to same school I did ... she was a year or two behind me.
In a link to an interview with Ed McMahon at speaking.com he mentions his early associations with WLLH and Lowell, Mass.
