"Old Blue"

I listened to Dr. Byrds & Mr. Hyde yester-day and noticed a couple small features.

In the repeated line "Blue chased a possum up a hollow limb" (with "hollow" sung more as "holler") in "Old Blue," the phrase "up a hollow limb" is usually sung to an ascending phrase (D E F# A B the first time and D E F# A D the third time), giving a sense of that "up."
