Cops burst into crack houses---and then burst into song---in this experimental police series, an ambitious and definitely odd musical dramedy that blends the sensibilities of Steven Bochco's 'Hill Street Blues' and Dennis Potter's 'The Singing Detective.' The Bochco-produced series debuted in 1990 amid much fanfare, but audiences weren't ready for the jarring experience of watching crooks and cops crooning. It lasted three months.
