Was under the impression that the Chanty version of "Strike the Bell" (Second Mate) predated WORK's 1865 version; it was not uncommon for writers to "borrow" folk tunes running around at large and take credit for them by the act of writing them down and publishing them. The Classical Masters were not at all above doing this, occasionally alluding to the work being "based on" or "an arrangement of" something born of common folk. Guys like Brahms and Beethoven, I'm told, used to travel about various European fairs, festivals, and pubs with a notepad and ready pen to jot down themes of whatever musical vulgarities with potential wafted their way. My studies of Civil-War period music suggests that this practice was still very much alive at that time. Being familiar with both versions, I far prefer the Sea Shanty.
