After a long, hard fight battling cancer, Cheryl Bentyne rejoins Manhattan Transfer for their summer tour, her jazz-and-swing voice still as magnificent as ever. The quartet also includes rock-and-roll-influenced Tim Hauser, doo-wopping since he was 15 with an extensive discography of his own; Alan Paul, part of the original Broadway cast of Grease; and folksinger Janis Siegel, fusing jazz and pop in perfect pitch. Truly timeless even after 40 years, the Transfer is still releasing top-selling, Grammy-winning material. Bask in hits like “Birdland,” “Java Jive” and others on Friday, Aug. 17, at Uptown Theatre. 1350 Third St., Napa. 7pm. $50. 707.259.0123.
