This is a "just the facts" analysis of how the Dead historically used The Other One as a vehicle to introduce what one could argue as the coup de grâce of the show (the figurative, not the literary meaning 😉) - the Garcia ballad. It no surprise that Wharf Rat was far and away the most common paring, but I had a notion of measuring that against the other titans. So with a prerequisite shout out to https://www.gratefulsets.net , I present the following numbers....
The Other One ->
Wharf Rat (164 times)
Stella Blue (85)
Black Peter (35)
Morning Dew (22)
Comes A Time (10)
GDTRFB (9) - ok, not technically a ballad but sat in for one here and there
Sing Me Back Home (8) - this surprised me
The Wheel (6) - see GDTRFB notation
Days Between (5)
China Doll (4)
Standing on the Moon (4)
The transitional jams creating these segues are of course infinately more meaningful than any sheer numbers, and there are a few beauties off the top of my head, but that's what makes listening to Jerry's most tender moments so interesting vs. simply delineating them numerically. And moreover, one couldn't count on such a jam; often to be fair it was just The Other One clumsily pounding into a ballad. Exhibit infinity of why you never wanted to miss a moment. 😍
