He's a big dealer, consistently listing and selling thousands of records. He probably hasn't given it much thought.
The song your 45 plays is "Oh, How I Love You" written by J.W. Alexander on SAR 156.
The label on your 45 reads "Keep On Lovin' You" written by Charlie Julien on SAR 156.
It's incorrect.
SAR 156 was obviously scheduled to be released with the 'Keep On Lovin' You' side coupled with "Run, But You Can't Hide" and then changed to "Oh How I Love You".
But labels were printed for "Keep On Lovin' You" and some copies were pressed up with that incorrect label, before it was switched to the correct label "Oh, How I Love You".
SAR 156 was the penultimate release on the label. There was obvious confusion around the time of Sam Cooke's death, when the label folded and "Keep On Lovin' You" was never released on the label, which is a shame as its a great song.
