The glut of shows looking for homes on Broadway has gotten so bad that an $8 million revival of one of the Great White Way’s biggest smash hits ever has been reduced to begging for performance space. A Chorus Line, which ran on Broadway for 15 years, is slated to open in fall 2006, but it hasn’t even been able to get signed as a backup booking. In addition to the booking jam, “there is also the question of just how well A Chorus Line has held up over the years and whether audiences will flock to see a revival of a show that hasn’t been gone all that long (it closed in 1990).”
