Thanks for throwing in the Demeters I had requested! It's appreciated!
A little tidbit about "Ouch" on D-23/24, though -that timp/slide whistle effect actually predates the Demeter library's formation in the 1960s, showing up in a 1954 sound reissue of a Felix the Cat cartoon at 6:54
Not so coincidentally, "Frank Gartner" himself, Frank Lewin, is credited as piecing together this new music and effects track, implying that some of the Demeter tunes are actually short music stings and effects he took from his old employer, Jack Shaindlin's Langlois Filmusic. I have a feeling "Down the Steps" on the same album is another something taken from a Felix short he worked on, considering it's basically an edited-together sequence of some woodblock "bonks" and a sighing musical sting.
