This song is also the source of a widespread mondegreen or two.
The line "(I) can't walk for running" tends to be often misheard, so when you see the "lyrics" to this song posted online or typed up elsewhere, you will find that line morphed into things like:
"Hockey walls a-runnin'" or "Cane foam's a-runnin'" or other similar non-sensical lines.
I think it comes from singers pronouncing it like "Ah cain't walk fer runnin'." or
