Gene Pitney - It Hurts To Be In Love

KRLA, the old rock blaster at 1110 kilocycles proclaimed August 23, the day of the Beatles' concert at the Hollywood Bowl as "B-Day in Los Angeles." That evening, as the concert was going on, the station's playlist alternated Beagles songs with new releases, or as the station called them, "picks to hit." One of these was "It Hurts to Be In Love," which I heard for the first time that evening.
Neil Sedaka - It Hurts To Be In Love (unreleased at the time, and better than Gene Pitney’s, me thinks.)
