WIP's best-known contest was Cash Call, a call-out game in which the DJs picked numbers out of the phone book or from postcards submitted by listeners. The intro to the contest was the first 10 seconds of a song called "The Sound Of Money" by the J's with Jamie, a vocal group that recorded many commercial jingles and three albums. If the person at the other end of the call could identify the exact amount of money in the “jackpot,” down to the standard 61¢ ending, they won the current jackpot. Players who knew the 61¢ but not the dollar amount typically won a token prize from a sponsor. Every incorrect guess lead to a few dollars being added to the jackpot; a correct guess resulted in the jackpot being reset to $61.61.
