Tonight’s episode #2 of Def Poetry on HBO will feature the usual mix of newcomers, seasoned spoken word veterans and a couple of celebrity drop-in poets, this time including John Legend and Alicia Keys. We’ll post a review tomorrow, and we’d like to invite you to contribute your review as well. The show is on at 11:30 pm EST, and again an hour and a half later for anyone just straggling in from a night out. Your comments are very welcome …
