Members of the Chicago Symphony Orchestra, Lyric Opera Orchestra and civic-minded volunteers offer a musical tribute to the area’s frontline workers with an original arrangement of Fred Fisher’s “Chicago” — most famously popularized by Frank Sinatra, but also beloved as a ballpark/stadium staple in this Toddlin’ Town. Playing in the band are David Griffin (horn) and Michael Mulcahy (trombone) of the CSO; Susan Warner (clarinet) and Collins Trier (bass) of Lyric Opera, Henry Griffin (vocals) and Francis Bassett-Dilley (drums). Video production by Liam Loughran.
