If you can do a cockney accent, try singing “Get me to the Church on Time”. This song is for an older Baritone of Bass. It’s rather easy so if you don’t have that wide of a range try this one. Norbert Leo Butz is playing him in the 2018 revival. He was the original Fieyro in Wicked and has played other roles like Roger Davies in Rent and Edward Bloom in Big Fish.
