In addition to the two or three songs referenced above, a *lot* of the Grateful Dead repertoire consisted of traditional covers (e.g., "I Know You Rider," "Oh Babe It Ain't No Lie). They were originally a jug band, after all.

However, many of their other songs whose titles quote from traditional sources are in fact newly composed Hunter-Garcia pieces (e.g., "Shake Sugaree"). Like many more "purist" folkies, they were making an honest effort to write within, and contribute to, a time-honored tradition.

Then there are the many not-quite-folk songs they did: folk-revival-era originals, like Bonnie Dobson's "Morning Dew"; and blues/R&B standards, like Bobby Bland's "Lovelight." Well, maybe the Libba Cotton song I mentioned above is not truly traditional, but falls into this category.
