Montgomeryville, Pa. - Bob and Ron's World Wide Stereo will welcome members of R&B band Earth, Wind & Fire to the A/V dealer's main showroom here Thursday night as part of a 40^th anniversary promotion sponsored by Monster.

The "VIP Evening" event will include prizes, promotions, product demos, Philly-style food and an autograph signing session with the musicians.
