Known to his friends as Bob Adams, the aspiring actor/radio DJ spent just a couple of years attending Bishop Duffy High School before dropping out and moving to New York City at the age of 17 to study acting.
It wasn't until Shannon arrived in Phoenix that he garnered his first major success at KRUX by rapidly climbing to number one in the market by beating all competitors by twenty plus points,[1] utilizing a variety of crazy characters and outlandish antics such as the invasion of his show by the television rock group, The Monkees.
Following his departure from Phoenix, Shannon held air shifts at WKBW Buffalo, New York and WKYC Cleveland, Ohio until landing the coveted early evening slot at KXOK St. Louis, Missouri where he again rose to the number one show in the market,[2] beating his nearest rival by over twenty ratings points.
Following St. Louis, Shannon joined a couple of famous stations, including KJR Seattle, Washington, WIXY Cleveland, Ohio and KDKA, before returning to KDWB Mpls/St.Paul as "BS" in the morning.
His name recognition eventually brought him to the attention of KFI Los Angeles in 1975, where he enjoyed several successful years doing afternoons as "BS in Drive".
He was cast in a variety of shows, including Hotel, The Practice, Archie Bunker's Place, General Hospital, Kojak and Hill Street Blues.
From the 1980s to the 2000s, Adams appeared in dozens of film and television projects including Rocky IV, The Execution, Falling Through, and Murder, She Wrote, and was a series regular on Riptide.
Adams appeared as a panelist for the Screen Actors Guild Foundation and conducted SAG-AFTRA acting workshops in Los Angeles and San Diego.
