(concurring) :
I concur fully in the court’s action and all of the opinion but in view of my recent recantation in Moore v. United States, 5 Cir. 1968, 394 F.2d 818, of my acquiescence in Williamson v. United States (Williamson II), 5 Cir. 1965, 340 F.2d 612, I renew and republicize my Williamson I, 5 Cir. 1962, 311 F.2d 441, 445, opposition to these contingent fee arrangements.
