Here is the classic Flatt & Scruggs recording of 'Down The Road' that I mentioned at last night's jam that every Bluegrasser, especially every Bluegrass banjo player, should be familiar with:
Down the road - Earl Scruggs:
I first heard 'Down The Road' on a cassette tape that I purchased back in the early 90's at a Bluegrass Cardinals concert: the band on the tape consisted of a couple of members of the Bluegrass Cardinals, and a few members of the Del McCoury Band: their version of Down The Road was clearly influenced by the old Flatt & Scruggs arrangement (as evidenced especially by the choice of banjo licks for the banjo breaks and backup parts, and by the unusual way of ending a vocal number), and I have found that to be the case with nearly all arrangements of Down The Road from top-notch Bluegrassers.
Here's an example of this from the Bluegrass Album Band - Down the Road::
...and another good example from The Bluegrass Cardinals (live performance)
