We've never had this much Billboard Chart power in the Undercover arena before: Richard Marx conquered pop music in the late '80s and early '90s, penning and performing songs like "Don't Mean Nothing," "Should've Known Better," "Hold On To The Nights," and "Right Here Waiting." Matt Scannell leads a band called Vertical Horizon, which had a massive hit in 1999 with "Everything You Want." The two have been friends for years, and since Marx is a Chicago guy, it was easy enough for them to join us at the Undercover studio for a rendition of the Burt Bacharach/Hal David classic "What's New Pussycat," which was originally performed with sexy/sleazy appeal by Tom Jones back in 1965. A big audience gathered for the performance, which led to another performance—of Marx's relatively recent hit "When You Loved Me"—which you might get to see at a later date. Enjoy.
