nosuchdragon5 - Comic Tension (a) by Dick Walter [KPM 1329] (1st part, 2nd part unknown)
Still unsure of that as it could be an entire track from a different library (possibly by the same composer).
Anyways, I've found a couple new tracks from Bruton BRG 14 "Simple Songs": "Open to Offers" by Brian Bennett (monster_fair5, school2) and "Cute" by Brian and Warren Bennett. (school3)
EDIT: With the help of the AHA Music Identifier, I was able to identify another Brian Bennett track, this time from KPM 1128 "Counterpoint in Rhythm": "Prelude and Groove Part 1" (thumbelina6). And it seems that I have left out one last one unknown track from "Get Ready For School", which I have now added to my Dropbox folder.
EDIT 2: I also found out that "Polka Continental - Short Version" (aka Polka Dotta [#63] on Carlin CPM 3 - Panorama Idents Kitsch Jazz Travel) by William Loose and Emil Cadkin plays in the
Richard Scarry's Animal Nursery Tales segment, "The Gingerbread Man", albeit 5 semitones higher. Now adding the remaining unknown tracks of "Three Homes For Two Puppies" from
Pound Puppies Tales Featuring The Newborns.
