Opinion by

On January 29, 1972, at approximately 1:00 a.m., George Ware was fatally shot at a bar known as the “S and C Lounge,” located at 1326 West Girard Avenue, Philadelphia, Pennsylvania, by appellant, Andre Monroe. The Commonwealth’s evidence disclosed that prior to the shooting, one James McCoy and another man were seated at the bar when they were approached by two women, one of whom was appellant’s sister. The *592women took seats next to the two men and ordered refreshments. A conversation started among the four, which ultimately became an insult match between appellant’s sister and James McCoy. Appellant, who was present at the bar during the conversation, approached McCoy and demanded to know why McCoy had insulted his sister. The bartender, upon observing that appellant and McCoy were becoming angry, and noting that McCoy had a gun, asked the men to leave the bar in order to avoid trouble. They immediately complied. Approximately twenty minutes later, appellant returned to the bar and asked the bartender whether McCoy was still there. The bartender replied that he was not. Appellant was then approached by three men, one of whom was McCoy’s brother-in-law, Gregory Ware. Ware identified himself as McCoy’s brother-in-law, and asked appellant if he was looking for trouble. Appellant quickly drew a pistol and fired at Ware, causing his death. Appellant, waiving his pistol, then left the bar. He was subsequently arrested and convicted by a jury of murder in the second degree. After denial of his post-trial motions, appellant was sentenced to ten to twenty years in prison.

Appellant, in this appeal, argues that the trial court erred when it refused to give appellant’s requested charge relating to voluntary manslaughter. We agree.

At the time of appellant’s trial, a defendant was not entitled to a charge of voluntary manslaughter, unless there was some evidence in the case which could support such a verdict. See Commonwealth v. Davis, 449 Pa. 468, 297 A.2d 817 (1972), Commonwealth v. Matthews, 446 Pa. 65, 285 A.2d 510 (1971). Now see Commonwealth v. Jones, 457 Pa. 563, 319 A.2d 142 (1974).

We believe that there was evidence which could support a verdict of voluntary manslaughter in this case. As previously related, the testimony disclosed that twenty minutes before the shooting, appellant had seen *593the victim’s brother-in-law, McCoy, with a gun. Even though appellant did not take the stand, the jury could have inferred that when appellant saw Ware and two other men advance toward him in a threatening manner, appellant’s act of quickly firing his gun might have been motivated by a fear that his life was in danger. Even if this fear were unreasonable, if it actually motivated appellant, his crime would be voluntary manslaughter, not murder. See Commonwealth v. Miller, 448 Pa. 114, 290 A.2d 62 (1972), Commonwealth v. Principatti, 260 Pa. 587, 104 A. 53 (1918).

Judgment of sentence reversed and case remanded to the Court of Common Pleas of Philadelphia for a new trial.

Concurring Opinion by

I concur in the grant of a new trial. It is my view that constitutional error occurs* when in a murder *594prosecution a trial court refuses to deliver a requested charge on voluntary manslaughter, regardless of the presence or absence of evidence tending to prove the distinguishing elements of voluntary manslaughter. This was the situation here.
