I have put O Sifuni Mungu on the website It is quite complex, with all the repeats and such, so I hope I got it mostly right.
My software can't handle situations where a note is tied across an alternate ending (e.g., measures 17, 66) so I had to rearrange things a bit. So my version won't look exactly like the printed page but it should play correctly. (This shouldn't be a problem, since you should probably be looking at the printed version when using the site. The display on the site is only to help you navigate around, in case you want to repeat a section to burn it into your brain, etc.)
See you Wednesday,
