Al Green is taking over pharmacies nationwide.

The soul singer known for '70s hits like "Let's Stay Together" and "Love and Happiness" graced a Walgreens sign in Pennsylvania. The addition is the work of street artist Cassius King, who frequently decorates West Chester, Pennsylvania with vinyl adhesives and projections.

Green thought it was hilarious.
