PETER, PAUL AND MARY
From Wikipedia:Peter, Paul and Mary were a United States folk-singing trio whose nearly 50-year career began with their rise to become a paradigm for 1960s folk music. The trio was composed of Peter Yarrow, (Noel) Paul Stookey, and Mary Travers. After the death of Mary Travers in 2009, Yarrow and Stookey continued to perform as a duo under their individual names.
"Early in the Morning" was used in the series 'Mad Men', at the end of the episode "A Night to Remember".
