Concurring statement by
KELLY, Judge:I join that portion of the opinion which rejects the defendant’s assertions on appeal. I concur in the result as to the reversal of the trial court’s grant of a new trial. I believe the characterization of the limits on expert testimony is overbroad. See Commonwealth v. Thek, 376 Pa.Super. 390, 546 A.2d 83 (1988); Commonwealth v. Pearsall, 368 Pa.Super. 327, 534 A.2d 106 (1987). Nonetheless, I wholeheartedly agree that the reference in this case did not warrant the grant of a new trial.
