My dad used to have a record of traditional sea shantys. When I was a kid it was my famous record to listen to and I knew the words to a lot of the songs. My dad knew a lot of the words too and sometimes we would sing together and dance around the living room like pirates.
Unfortunately one day the record broke and it was so old and unusual that there was no way to replace it. I have been able to find a lot of the music as MP3s but it is not the same as listening to it with my dad.
