Opinion

In this appeal involving a robbery conviction, the colloquy covering appellant’s alleged waiver of a jury trial was not recorded, and the record in its entirety will not sustain a finding of a knowing and intelligent waiver of such right. Commonwealth v. Williams, 454 Pa. 368, 312 A. 2d 597 (1973); *731Commonwealth v. Lockhart, 227 Pa. Superior Ct. 503, 322 A. 2d 707 (1974).

Judgment of sentence reversed and new trial granted.
