At the second performance, Robbie Williams took the stage. He and Taylor sang his trademark song “Angels” together. “Angels,” for the uninitiated, is a song about Williams’ decision to love angels as a way of protection. (I think.) Williams emerged from the ‘90s boy band Take That in 1996 after some legal turmoil — boy bands always dissipate painfully, you know? He went on to become Britain’s best-selling artist. “Angels” is his popular recognizable single, and the record that launched his solo career. Take That, for the record, is still together! They did ain 2017.
