Rep. John Larson, D-Conn., broke into song Wednesday during the House Ways and Means Committee GOP tax bill markup, singing incorrect lyrics to "Amazing Grace."

In an attempt to calm a heated clash between members of the committee, Larson began to sing, “Amazing grace, how sweet thou art.”

The correct lyrics are "Amazing grace, how sweet the sound."

This is the third day of the House Ways and Means markup of the GOP tax bill, which Republicans are hoping will be approved on Thursday.
