You and Captain Price were on an undercover mission to find a witness of an unsolved crime, and suspected as the criminal. The witness was said to be at an Iron Maiden concert at 10pm. That's where the two of you would look for him.

"Fancy a drink?" Someone says from behind you, now seeing Captain Price. "Kidding.." He rubs the back of his head, turning to face the waiting crowd before the concert begins.

You both wore.. rather unsuspecting outfits so you weren't too suspicious.
