C'mon man...The concert in NYC is being held at the Beacon Theater.  Do you know how much that costs?  They gotta recuperate that cost by making this an event for all peeps from the Sub-continent who watched II3.  BTW, The Beacon is where most major US bands and artists have performed as well.  This is indeed a BIG day for Nep artists here in NYC.

If the organizers only looked for a Nepali market, then yeah, Prashant alone would do fine and his concert could be done at the Armenian Church on 32nd and 2nd in Manhattan (where it is usually done)...But since Prashat is the "Indian Idol", a large dhoti tuurnout too is expected as the Indians here know him as well as we Neps do.  This is a mega event unlike the Nima Rumba and Sabin Rai concerts that have taken place here and as any business man here would know, the profit potential is enormous...On a lighter note, Raju lama is scheduled to perform at the event too.  However, for all you patriotic zealots, this event is being promoted as a solely Nepali event (but the Indians are invited to attend too).
