ABC in Concert is a revival of its old "Wide World of Entertainment" series from the 70's, this ABC series presented concert performances featuring a different rock or pop performer each week. Musical acts ranged from well-known performers like The Rolling Stones and Cher, to newer, up-and-coming acts like New Kids on the Block, Sinead O' Connor and Mariah Carey. These late-night concerts were also simultaneously broadcast on ABC radio.
