Crowds thronged for tickets after a surprise announcement that Guns N' Roses would play a concert Friday night at West Hollywood's famed Troubadour music venue.

The band announced on its website and in a press release that a limited number of tickets at a very old-school price of $10 apiece would be available at noon at the former location of the famous Tower Records store on the Sunset Strip.

TV news helicopters showed a long line of fans stretching from the store and down the street.

The band, which formed in the mid-1980s, is about to embark on a reunion tour featuring Axl Rose and Slash.
