First of all, was it ever released with yellow harp labels? The album was recorded in early 1960, and received the catalogue number it would have had had it been released that year, just before 'The 25th Day of December with Bobby Darin'. However, it was held for release until June 1963, by which time the harp label had been replaced with the bicolour one. I've never seen a copy of this LP with the harp labels, though I've seen in more than one place that it was first released with them. I wonder whether the persons who say so are misled by the catalogue number, or whether it was really so.
The second thing I'd like to ask you about is the back side of the sleeve. I've seen two variations: one (shown here) with no song list in the right side, and another with the song titles in a blue box. Why is that so? I've seen an eBay listing whose photo shows the cover with the blue box, but the seller says that it's been glued onto the sleeve to cover a printing mistake in the song order. Is this right? Are all sleeves with the blue box really stickers? If it's so, were seeves without the song titles released first, and then someone realised that there was no song list in the sleeve? Or were they always released with a sticker, and whenever we see a sleeve without it it's because someone's peeled it off?
