I need the correct lyrics for this song. I could catch most of it from a recording but there are still some blanks. Would appreciate any correction or help. Thanks.

One bright early morn in the month of May
Under the old linden tree
We danced and we sang till the end of the day
Under the old linden tree
We sat in the branches do sturdy and strong
And filled all the air with a yodeling song

Chorus: ...(don't know)...

...everyone ran when it started to rain
Under the old linden tree
We...till the sun shined again
Under the old linden tree
And when we were hungry, we'd...to eat
And we were thirsty we'd cider so sweet

We made pretty garlands to put in our hair
Under the old linden tree
The boys are so sturdy the girls are so fair
Under the old linden tree
And when we went home at the end of the day
We walked arm in arm as we sang all the way
