Phunking with our hearts

Fergie may have ditched the Black Eyed Peas, but it didn’t feel official until “Will.i.am and Friends Featuring the Black Eyed Peas — Landmarks Live in Concert: Great Performances,” recorded at London’s Royal Albert Hall. With the help of guests, the group manages to get through hits like “Let’s Get It Started,” but it’s a shame to hear them without its charismatic lead singer, especially considering that she’s committed herself to hosting subpar reality shows like “The Four.”

The recent death of producer Steven Bochco should have triggered more appreciation for “Hill Street Blues,” the most ambitious drama in network TV history. If you still need convincing, check out the 1983 episode “Here’s Adventure, Here’s Romance,” in which a detective is reluctant to come forward after witnessing a double murder in a gay bar. The homophobia may be dated; the impact is not. Repeats can also be seen on the Heroes and Icons channel at 2 p.m. weekdays.
