X can play just fine...its Richie's stage presence, his style, his stardom (the 'it factor') and his vocals/harmonies I miss the most. My last 4-5 shows (the end of US Circle tour) and 3 in April this year have all been X, and while I enjoyed them and am pumped for Soldier Field and Vegas, I'm ready for Richie to return...I'm thinking Soldier Field for the return.
