By Andrew Travers, The Aspen Times Actor and comedian T.J. Miller headlined a sold-out Belly Up on Monday night in one of the Denver native’s first returns to stand-up since allegations of sexual assault were made against him in December. Miller didn’t directly address the allegations in his Belly Up set, which ran just over 90 minutes and stuck largely to local material that played well to a receptive Aspen crowd. He discussed his recent turmoil only obliquely.
