Hmm, to find an old song is hard. There are many "ways", but i believe any Clubsnap member can't tell you the "other" way, except to look for the original. Clubsnap, practices anti piracy rules. Try looking at Bras Basah road? There are some shops who do track conversion to mp3 formats.
This song is not from the 50s.. It is from the 1979. You can buy it off itunes (99cents only) and many sites if you do a search....unless you are asking for someone to "give" it to you. heheh You can't do that on CS nor ask for a bit torrent link to it.
