The first time Mahala Morefield met Weasel, aka Jonathan Gilbert, she was a law firm receptionist posing as a music writer from the Lone Star Dispatch. It was 1975. Morefield had relocated to Washington, D.C., from Austin and stumbled across a high-pitched nasal voice spinning records on an eclectic midnight to 6 a.m. show at a 3,000-watt station with the call letters WHFS (“High-Fidelity Stereo”).

Little Feat, the Stones, Frank Zappa—a Romani-French jazz guitarist named Django Reinhardt with only eight good fingers—somehow it all fit together each night. “I had a musical crush on Weasel,” recalls Morefield. “I set up a phony 5 a.m. meeting and held on to the cassette tape of that ‘interview’ forever.”

Fast-forward almost 45 years. The WHFS days—including the later years when the station moved to Annapolis and blasted its new 50,000-watt signal toward Baltimore—are long past. The station’s epic HFStivals, of course, are gone, too. But Weasel, whose nickname was bestowed by an American University classmate who thought he resembled the creature on the cover of the Zappa-produced 1970 album Weasels Ripped My Flesh, is still on the air, spinning now for Towson University’s WTMD.

Because Gilbert doesn’t drive—he still lives in the same Bethesda building where the old WHFS studio was located and where its transmitting tower remains impaled on the roof—a revolving band of 50-plus volunteers, fondly referred to as Weasel’s Wagon Train, takes turns transporting the unlikely D.C.-Baltimore cultural icon to Towson to record his once-again, organic, free-range shows on WTMD. (Passionate, engaging, witty at the microphone, Gilbert isn’t quite a recluse off air, but he’s not on Facebook or other social media, either. “Why would I do that? I want to listen to music and I want other people to listen to music.”)
