William Royce “Boz“ Scaggs (born June 8, 1944) is an American singer, songwriter, and guitarist. He became prominent for his series of albums in the late 1970s, and songs “Lido Shuffle” and “Lowdown” from Silk Degrees (1976), which peaked at No. 2 on the Billboard 200. Scaggs continues to write, record music, and tour.

Scaggs was born in Canton, Ohio, the eldest child of a traveling salesman. Their family moved to McAlester, Oklahoma, then to Plano, Texas (at that time a farm town), just north of Dallas. He attended a Dallas private school, St. Mark’s School of Texas, where schoolmate Mal Buckner gave him the nickname “Bosley”, later shortened to “Boz”.

After learning guitar at the age of 12, Scaggs met Steve Miller at St. Mark’s School. In 1959, he became the vocalist for Miller’s band, the Marksmen. The pair later attended the University of Wisconsin–Madison together, playing in blues bands like the Ardells and the Fabulous Knight Trains.
