A pure heart—yes, quite an excellent thing, my friend, indeed, a pure heart is very excellent, but to stop there would be a mistake, a co-loss-al-mis-take! A pure heart is an excellent thing, but can we deny that there are many other excellent things, for instance, a clean shirt; a clean shirt is also an excellent thing! There can be no denying it; a pure heart and a clean shirt, these two go together like peas in a pod, at least insofar as excellence is considered! You look surprised, but just last Saturday I saw an old classmate who is now a collegiate secretary, and who has very bright prospects, and if you don't mind my saying so, an even brighter shirt! Marvellously clean! You know there are great things in store for a man like that, and so who can deny that a clean shirt is as excellent as a pure heart, perhaps even more excellent!
If I were John Hollenbeck, I would title a Claudia Quintet tune
Purity of Heart is to Will One Thing. A tune so titled could fit with their sound quite well.
