2) The Who, it would be a stretch
This one seems like even more of a stretch than Mumford & Sons. The Bonnaroo 2013 lineup clue No. 1 reads “Rising sun of man, The future was less certain, Human Contact is gone.” One Redditor interpreted this clue as follows, “The Who performing Quadrophenia.
Rising Son of Man – Jimmy growing up in his parents house before he leaves home. The Future Was Less Certain – Jimmy running from home and not being able to find a new one/everything letting him down time after time Human Contact is Gone – Jimmy stranded alone on the rock in Love Reign O’er Me.” Now the band will be in the U.K. in June, though it does have two open days on June 13 and 14.
