Many moons ago Mary Mary had a hit with Shackles (Praise you). They have released several singles and albums since then. Their newest single Walking has been in the Billboard charts for the past three weeks and it would be great to see it climb further. Mary Mary's brand of music is gospel pop but R'N'B has changed so much in the past few years and the market for more innocent old school R'n'B is one that I wish would come back into the charts proper.Here's Walking. and from their debut album Thankful here's the wonderful I Sings.
