The 1984-86 version featured a brand new theme provided by Score Productions, although original composer Sheldon Allman returned as music director for the first season. Todd Thicke replaced Allman in that role for the second season. Both music directors utilized music from previous Hatos-Hall shows, such as Split Second, as incidental cues during the show. The 2009 revival features another new theme composed by Brian Teed. Since 2011, keyboardist Cat Grey has provided in-studio musical accompaniment. Each episode of "Let's Make a Deal" consists of several "deals" between the host and a member (or members, generally a married couple) of the audience, referred to as "traders." Audience members are picked at the host's whim as the show moves along, and couples are often selected to play together as traders. The deals are mini-games within the show that take several formats. In the simplest format, a trader is given a prize of medium value (such as a television set or a few hundred dollars in cash), and the host offers them the opportunity to trade for another prize. However, the offered prize is unknown. It might be concealed on the stage behind one of three curtains, or behind "boxes" onstage (large panels painted to look like boxes), within smaller boxes brought out to the audience, or occasionally in other formats. The initial prize given to the trader may also be concealed, such as in a box, wallet or purse, or the trader might be initially given a box, envelope or curtain. The format varies widely. Technically, traders are supposed to bring something to trade in, but this rule has seldom been enforced. On several occasions, a trader is actually asked to trade in an item such as their shoes or purse, only to receive the item back at the end of the deal as a "prize". On at least one occasion, the purse was taken backstage and a high-valued prize was placed inside of it. Prizes generally consist of either cash or merchandise with genuine value, such as a trip, electronics, furniture, appliances, or a car. At times, a small prize (typewriter, pocket tape recorder, etc.) may contain a cash bonus or a written/recorded message awarding cash or a larger prize to a contestant who has chosen it. Certain contestants win booby prizes called "zonks," which can be outlandish items (live animals, junked cars, giant articles of clothing, etc.) or legitimate prizes with very little value (wheelbarrows, giant teddy bears, piles of food, etc.).
