Despite all the money you’ve spent on voice lessons for your great American novel, the otherwise charming tome still has a timbre that can only be described as “Gilbert Gottfried–esque.” Enjoy the melodic talents of a more musically inclined American lexicon with today’s deal: for $6, you get one ticket to Corpus Christi Live!’s The Great American Songbook, scheduled at 7:30 p.m. October 22 at the Performing Arts Center at Texas A&M University Corpus Christi (a $12 value). Enjoy a second-balcony view for a salute to classic made-in-the-USA melodies spanning the generations, from the iconic tunes of the Gershwins and Rodgers and Hammerstein to the Motown masters and beyond, along with show-stopping dance numbers, a 1940s radio-show scene, and a seven-minute Wizard of Oz. You can exchange your Groupon for a ticket at will call the night of the performance, and seating is on a first-come, first-served basis.
