Other than the beers/friends aspect I'm not having that it's the same or even similar to following a football team.
Football can give random, unexpected moments of joy and elation. There's also the anticipation and nerves leading up to a game against a rival or to win a trophy. A gig, although great just doesn't hit those highs the same way. Especially a gig that you've already been to if your following a particular tour.
A run of gigs watching different bands at a festival maybe might bring a level of anticipation that's similar but I can't see how watching the same set by the same band/artist would.
