Take $100,000.00 a week, divide it up among some of the brightest stars in entertainment, then add in top-notch writing, a full orchestra and choir conducted by Meredith Willson and hire a sophisticated, deep-voiced leading lady as your hostess and what do you get? One of the most amazing and entertaining variety shows ever to hit the airwaves: “The Big Show,” starring Tallulah Bankhead. Aired as a Sunday evening extravaganza, NBC literally broke the bank hiring stars for each 90-minute broadcast -- and it was, of course, simply too expensive to last. But while it did, it provided impressive entertainment, capturing the majority of the mid-20th century’s top performers at their peak. This third set offers shows 11 thru 15 of “The Big Show’s” first season, transferred from master recordings and restored for outstanding audio fidelity.
