concurring.
I join the majority opinion and, in view of the Concurring Opinion authored by Mr. Justice Larsen, which I also join, write separately only to emphasize that the views expressed in Commonwealth v. Williams, 490 Pa. 187, 415 A.2d 403 (1980) and Commonwealth v. White, 490 Pa. 179, 415 A.2d 399 (1980) do not differ in any respect.
