Tony Orlando

Between 1970 and 1975, singer Tony Orlando was one of the biggest stars in the music business, thanks to such highly polished pop-R&B tunes as "Candida," "Knock Three Times" and "Tie a Yellow Ribbon Round the Ole Oak Tree," which he recorded as part of the vocal trio Tony Orlando and Dawn. The act, which featured singer and later actress Telma Hopkins and Joyce Vincent Wilson, offered bright, sunshine-soaked pop music. But personal issues, including a struggle with substance abuse, forced Orlando to retire from music, bringing the act to an end before he resurfaced as a solo performer in the late '70s. He proved a capable actor in several TV-movies, as well as a popular attraction on the casino circuit. Orlando and Dawn reunited on several occasions in the 1980s and beyond, which underscored their lasting appeal as one of the more personable acts of the 1970s.
