Arthur Penhallow (born December 20, 1943) is a radio presenter in Detroit, Michigan who hosted afternoons on active rock station WRIF from 1970-2009. On March 30, 2009, WRIF owner Greater Media announced that the station and Penhallow had been unable to come to terms on a new contract.
Penhallow was born in Honolulu, Hawaii. Before beginning his long tenure with WRIF, Art had toured with a band that played with the Mamas & the Papas, among others. Under the name "Cicero Grimes", he worked at WNRZ in Ann Arbor in 1970, and then moved to WRIF's predecessor, WXYZ-FM, which at the time was airing a syndicated progressive-rock format distributed by ABC called "Love".
Penhallow was one of the "Love" format's local announcers and stayed on as WXYZ-FM transitioned to an all-local air staff and moved from progressive rock to the then-new "album oriented rock" format as WRIF.

Penhallow regularly refers to himself as "Big Daddy Arthur P" or simply, "Big Daddy", as do others on the station. Penhallow played himself in the film The Upside of Anger.

In January 2009, Penhallow's contract expired at WRIF and he was off the air for more than a month before finally releasing a statement on March 27, on his Facebook page saying: "It appears that my days in Detroit radio are over for now. Thanks for your support over the last 39 years....I shall return."
After months of negotiations, WRIF management and Mr. Penhallow were unable to come to an agreement on the terms of his contract. "We are disappointed that we couldn't come to a contractual agreement with Arthur," said Greater Media Market Manager, John Gallagher. "He is obviously a legend in the market and his many years of service to the industry are deeply appreciated. He will be sorely missed.”
