I don't remember playing this game, but the KLOV info for it sounds the same as you remember..
http://www.klov.com/game_detail.php?game_id=8242There are five separate games -- one for each band member -- plus a bonus round game. Each game has two phases: Recovering the musical instrument, and returning to the Scarab vehicle.
The games are as follows:
1. Steve Perry: Steve starts at the top of the screen and must make his way through a maze of moving turnstiles to his microphone at the bottom of the screen. Once he has the microphone, he uses the fire button to shoot at rows of passing turnstiles (similar to Galaga).
2. Neal Schon: Neal must navigate a cavern using his jet pack. Once he grabs his guitar, he must fly across the cave towards the exit while dodging rockets (similar to Scramble).
3. Steve Smith: Steve must jump back and forth between drums, turning them from yellow to blue. He then climbs behind his drum set and shoots bullets at flying infinity symbols (similar to Galaxian).
4. Jonathan Cain: Jonathan must make his way down conveyer belts, jumping piano keys (by pushing the joystick up). Once he is behind his piano, he shoots at vertical rows of circular objects that converge from the edges of the screen inward. Each object must be shot twice before it is destroyed (similar to Donkey Kong and Mega Mania).
5. Ross Valory: Ross jumps between elevators in an attempt to reach his bass at the top of the screen. Once he has reached there, he fires downward at cannons that are firing deadly LP albums.
Bonus Round (Concert/Herbie Herbert): Herbie, Journey's tour manager, must block the doorways and prevent the fans from entering any of the three doors on stage. If a fan gets past Herbie, everyone rushes the stage and steals the instruments again. During this scene, the machine plays a cassette loop tape of "Separate Ways."
