[78-L] Keynote Kuriosity

[Glenn Longwell]

Since Keynote has come up in recent posts I've been wondering about a recent find.
 
Last weekend I came home with the Keynote album of the Red Army Chorus of the U.S.S.R., Album 103.  The album lists 8 songs with lyrics on the inside of the front cover and the album has sleeves to hold 4 records.  Yet, the album had 5 records in it.  Four of them cover the 8 songs listed on the inside cover.  The fifth, the only that actually says Album 103 on the label, has two songs which are not listed on the cover.  This last record is K-207.  The others, which hold the 8 songs listed on the album are K-201, K-208, K-209, K-210.
 
I'm just wondering if they sold this as a 5 record album or you had to buy the 5th record separately.  Or perhaps they added it later and starting sticking two records into one sleeve to sell it as a 5 record set. You would think the numbers would be consecutive for the records with the songs listed.  Anyone else have this with the 5 records?
 
Thanks,
Glenn
