The rhyme-scheme in German should be the same. In best 'Teach Yourself' tradition:-

Ah Bay C(tsay) Day Eh efF Gay
Hah Ee Jot Kah lmno Pay
Q(koo) und erR und esS und Tay
U V(fow) W(vay) X(iks) Ypsilon tZet

There is the minor point that the last line of the tune is missing! I don't know the song but I suspect that U to Z are divided over two lines with various conjunctions thrown in.Still doesn't rhyme at the end though!
