Chevalier Theatre welcomes Air Supply, the Australian duo of Graham Russell and Russell Hitchcock, for a stop on their 50th Anniversary Celebration Tour. Air Supply is beloved for their 1980s soft rock hits including a run of five consecutive top-five singles: “Lost in Love,” “All Out of Love,” “Every Woman in the World,” “The One That You Love,” and “Here I Am.” They sold a total of 20 million copies of their first three albums and their 1983 Greatest Hits collection. Under musical direction of lead guitarist Aaron McLain, the ensemble also includes Mirko Tessandori (piano/keyboards/vocals), Pavel Valdman (drums) and Doug Gild (bass). Tickets are $69 to $115 through the Chevalier Theatre website/Ticketmaster beginning on Friday, January 17. To avoid online ordering fees, purchase tickets at the Chevalier Theatre Box Office, which is open on Fridays and Saturdays from noon to 6 p.m., as well as two hours before every Chevalier Theatre show.
