Hallelujahs on a Primary Chorus

I sing like a frog in a creek
just checking where I'm at
some notes sharp some flat
some things seem totally godsent
and then echoes remind me
I've read my biology front to zen
I realize the costs of buying and rent
and the joys of knowing how to bend
and guess that I'm just a bit of geology . . .
Keeper teach me the roads to heaven
all of my bread is toasted unleavened
and I sing the joys of just beginning
without considering the seismology
isn't someone else just as curious
and know that I am damn well serious
about where to go and where we've been?
