Every music festival is a gathering of the tribe.

You can identify the band of gypsies by their costumes: Tattoos. Tie-dye. Mohawks. Pompadours. All black. Flat-billed ball caps worn askew. Concert T's tracing the travels of bands and their followers.

But the third Vegoose brought together many tribes , thanks to the harmonic convergence of Las Vegas, Halloween weekend and a mash-up of musical genres.

All the regular tribes roamed the field next to Sam Boyd Stadium, providing plenty of off-stage entertainment.

Typical of the mix was the scene at the wedding chapel: Three couples, including a zombie bride and groom, exchanged these-don't-really-count vows as witnessed by Britney, a banana, a bandito, a butterfly, a bumblebee and Little Bo Peep.
