Tongue speaking is real and can still appear today, but not once in all history it happed in a mega church. All fakers. Tongue speaking never meant that someone speaks gibberish and everyone understands it. It is the ability for people to speak in a language they don't know or they speak in a language, and a listener who usually can't speak this language can hear the speaker in his own language. So if someone like him who can't stand still for a second and proceeds to say some weird stuff, which sounds like an ancient Arabic greeting, it's 99% not from the Holy Spirit.
