I'm not that good with cord choice , I sing at different levels , when the mood or song rings a bell in my vocal cords... but I learned "wave to me my lady " off a 78rpm record when I was 6 yrs. old by "Gene Autry " I used a '47 Philco radio / turntable unit.. I know where it is , and it still works , my niece has it now taking good care of it in Michigan , well that's history , what I need to know I some one who knows the song well enough to set me up with cords to play on my 12 string flattop . I'm thinking when Gene did the song in one of his movies it was in the key of "C" . Thanks to anyone who can help me out..bye ya'll
