Howie Doroughis bringing barbershop harmonies back…

The 46-year-old half-Puerto Rican singer and his fellow Backstreet Boys appeared on The Tonight Show Starring Jimmy Fallon, where they rocked some old-time threads for a special singalong. 

Dressed to the nines as a barbershop sextet, The Ragtime Gals (as they called themselves) sang Sisqo‘s”Thong Song” with an assist from Jimmy Fallon.  

It’s a fetching look in stripes and boater hats, and their a cappella version hits all the right notes. 

Earlier this week, the heavyweight boy band announced a second North American leg of their DNA World Tour.
