his name that appears on the credits for all but the initial release. Nonetheless, Beck has claimed credit for his contributions to the composition. Both Beck and Page agree that Page came up with the Boléro-influenced chords and rhythm. However, Beck specifically claims that key features of the instrumental—the haunting melody line and the second part "hard-rock" break—are his. Beck adds that the break contains "the first heavy metal riff ever written and I wrote it". While not addressing the specifics, Page asserts "I wrote it, played on it, produced it ... and I don't give a damn what [Jeff] says. That's the truth", but adds "the slide bits are his". Beck later put it behind him, "No, I didn't get a songwriting credit, but you win some and lose some down the years". Over the years, he and Page have made several appearances together in concerts and for interviews. Legacy Beck, Page, Hopkins, Jones, and Moon were pleased with the outcome of the recording session and there was talk of forming a working group and additional recordings. This led to the famous quip, "Yeah, it'll go down like a lead zeppelin", which Page later used, with a slight spelling change, for his new group. Page ascribed it to Moon, while Beck's and Led Zeppelin's later manager Peter Grant claimed Moon used the phrase "go down like a lead balloon", to which Entwistle added "more like a lead zeppelin". Group biographer Keith Shadwick notes that forming an actual group at the time "was never a realistic option", due to existing contractual obligations. For all their attempts at secrecy, Townshend learned of Moon's move. Beck recalled, "I remember [Pete] Townshend looking daggers at me when he heard it ... because it was a bit near the mark. He didn't want anybody meddling with that territory [his band, the Who] at all". Townshend also took to referring to Beck and Page as "flashy little guitarists of very little brain" for their perceived subterfuge (Page responded with "Townshend got into feedback because he couldn't play single notes"). In a later interview, Townshend explained Differences with Moon were resolved and he returned to the Who shortly after the recording. One month later, Page joined the Yardbirds and together with Beck became one of the first dual-lead guitar teams in popular rock. In 1968, Hopkins became a member of the Jeff Beck Group and for
