“1000”

LORELAI: We must be getting close, we’re running out of rows.
SOOKIE: And 1000. Okay, we’re here.

In real life, the theatre the concert scenes were filmed at, The Wilshire Ebell Theatre in Los Angeles, is a small intimate venue, and not 1000 rows high (in fact nothing is 1000 rows high). Sookie is just joking – we can see they are only in Row 22.
