If Anyone Who Had a Heart were to piece together a medley of Burt Bacharach songs at 30 seconds a song, the performance would last five hours. (In the Land of Make Believe, that would be The Beginning of Loneliness, because Only Love Can Break a Heart.)

And Bacharach, for those not familiar with the eight-time Grammy winner, is a love buffet. Along with lyricist Hal David, he nearly defined the sound of radio for decades. Point is, the songwriter, now in his 80s, is so famously and successfully prolific that an evening of just his full-length hit songs would triple the length of a usual Vegas show, meaning that his January 20 performance at the Smith Center will leave some music unsung.

But that’s the price for having an American icon onstage. Accompanied by three singers and a backup band, even if Bacharach taps into only a sliver of his repertoire, fans will likely be throwing him Baby It’s You looks and knowing that Long After Tonight Is All Over, What the World Needs Now is The Look of Love.

Burt Bacharach January 30, 7 p.m., $29-$125. Smith Center's Reynolds Hall, 702-749-2000.
