Jimmy Fallon is breaking the internet again this morning!  He and Billy Joel used iPads to form a 2-man Doo-Wop group and now their Jam session has gone viral!

If you've been missing Richie Phillips on The Sean and Richie Show this week, well, he took off the entire week so he could stay up late last night for Fallon!  I'm sure he'll say it was worth it!  Maybe next week on Write-a-Song Wednesday Richie will use iPad's only?!
