Lyric discussion by .one.last.try. 

the line about your knees is talking about having to grovel and beg for a break sometimes... it isn't easy in the music industry, and this song captures the lives of all the struggling artists out there, bartending, waitressing and trying to do shows and get the word out on them. Its everyone's dream in the industry to write home and not need the money anymore... I love this song seeing as I was one of those struggling a few years ago... makes me wish i hadn't given up

@.one.last.try. About "remembering what your knees are for," I think, means praying.
