The youngest member of the Hanson brood, 23-year-old Zac, steps away from the drum kit to belt out a pretty decent cover of Journey’s Don’t Stop Believing at the Hanson show in Tulsa, Okla., on Wednesday.

At about :48 into the clip, he can see him grab his peen and say “All I need is tighter pants.” INDEED! The trio has blossomed from girly-looking preteen punchlines to 20-something hotties.
