Katy Perry has never let us down when it comes to live performance. Her debut show in Bangkok last night (10 April) was jaw-droppingly vigorous. The pop diva brought her latest hits and all-time favorites—from "Bon Appetit" and "Swish Swish" to "Firework" and "California Gurls"—to sing, dance, and have a good laugh with her Katycats.
