We commend Harry Crane on his review paper which serves to not only point out the ubiquity of the Ewens sampling formula (ESF) but also highlights some connections to more recent developments. As pointed out by Harry Crane, it is impossible to cover all aspects of the ESF and its relatives in the pages generously provided by this journal. Our task is to present additional commentary in regards to some, perhaps not so well-known, related developments in Bayesian noparametrics.
