However, the tour did enable the band to meet and socialize with a number of top English groups, including the Rolling Stones and the Beatles. In particular, the band's relationship with the Beatles would prove important for both acts, with the two groups again meeting in Los Angeles some weeks later, upon the Byrds' return to America. During this period of fraternization, the Beatles were vocal in their support of the Byrds, publicly acknowledging them as creative competitors and naming them as their favorite American group. A number of authors, including Ian MacDonald, Richie Unterberger, and Bud Scoppa, have commented on the Byrds influence on the Beatles' late 1965 album "Rubber Soul", most notably on the songs "Nowhere Man" and "If I Needed Someone", the latter of which utilizes a guitar riff similar to that in the Byrds' cover of "The Bells of Rhymney".
