Hey Guys,
I was one of the organizers for TBP 06 when we brought Cheema to Jersey, and I just want to echo what everyone here has said -- he is absolutely amazing. He sang live on stage (no lip singing), and he sang at the Team Mixer without a dholi or chimta player or any other instrument. We basically just asked him to do something special for the teams, and he sang (I believe) what was at that time a song that was upcoming on his newer album.
The day of the show we had him sign pictures of each team and he wrote personalized notes to each team. And he was not high maintenance at all -- he spent most of his time that weekend just hanging out with our parents and eating our home cooked food. He didn't bring his own dholi, so we had Nana from PPA meet with him the day of the competition and they were able to work together for an amazing performance on stage.
I wish we had more people at the show that year, but I highly encourage another competition to bring him out!
