I tried running it through ghostscript:
$ pdf2ps African-Symphony-Baritone-C.pdf out.ps
$ ps2pdf out.ps out.pdf
$ pdfimages -list out.pdf
page num type width height color comp bpc enc interp object ID x-ppi
y-ppi size ratio
--------------------------------------------------------------------------------------------
1 0 image 4800 6959 gray 1 1 ccitt no 8 0 600
600 105K 2.6%
2 1 image 4800 6959 gray 1 1 ccitt no 14 0 600
600 86.4K 2.1%
Not only has it converted it to a standard image, it has also encoded the
images with CCITT which gives better compression for 1 bpc images compared with
Flate.</pre>
