While the band waited for "Mr. Tambourine Man" to be released, they began a residency at Ciro's Le Disc nightclub on the Sunset Strip in Hollywood. The band's regular appearances at Ciro's during March and April 1965 allowed them to hone their ensemble playing, perfect their aloof stage persona, and expand their repertoire. In addition, it was during their residency at the nightclub that the band first began to accrue a dedicated following among L.A.'s youth culture and hip Hollywood fraternity, with scenesters like Kim Fowley, Peter Fonda, Jack Nicholson, Arthur Lee, and Sonny & Cher regularly attending the band's performances. On March 26, 1965, the author of the band's forthcoming debut single, Bob Dylan, made an impromptu visit to the club and joined the Byrds on stage for a rendition of Jimmy Reed's "Baby What You Want Me to Do". The excitement generated by the Byrds at Ciro's quickly made them a must-see fixture on L.A.'s nightclub scene and resulted in hordes of teenagers filling the sidewalks outside the club, desperate to see the band perform. A number of noted music historians and authors, including Richie Unterberger, Ric Menck, and Peter Buckley, have suggested that the crowds of young Bohemians and hipsters that gathered at Ciro's to see the Byrds perform represented the first stirrings of the West Coast hippie counterculture.
