For the first time ever, BON JOVI will perform an entire full-length concert as an ACOUSTIC SHOW. The JANUARY 19th, 2003 concert scheduled in YOKOHAMA ARENA in YOKOHAMA, JAPAN has been announced as an ACOUSTIC CONCERT. It's a rare treat for Japanese fans and if there's any band that EXCELS in the acoustic format, it's BON JOVI! (The event will be captured on audio and video for the archives.)

& So the build up for the Tour hots up.
