What Did Hadley Fraser and Ramin Karimloo Share at the Phantom and Les Misérables Anniversaries?

At both anniversary performances, Les Misérables and The Phantom of the Opera, Hadley Fraser and Ramin Karimloo stood side by side for the bows. Fraser says they acted like children. One would stand on the other's toes, or an elbow would dig into a rib, and both would try to keep a straight face. He calls the shoving part of the joy of those nights, not a lapse they regret. The bows are the specific thing he says they shared at both anniversaries. The speeches came after, and he tells those separately. The physical bit in the lineup is the memory he pairs across the two shows.
