With the recent inclusion of "Alexander The Great" in Iron Maiden's setlists, which represented a 37-year gap between its studio release and first live performance, I was thinking about other such feats. I was at the show when the Grateful Dead" busted out "Unbroken Chain", but that is paltry in comparison at only 21 years.
I have compiled a list, generated from longest touring bands. One caveat is that the tune has to be a band original, not a cover. Another is that the band at the relevant point had to be made up substantially of original members.
Am I missing any? Not sure this would work in jazz contexts (unless Pat Martino played tunes from Baiyina in the new millennium?)
