Alongside (the Don't Care if I Never Get Back remix) is a version of
celli's
Prequel (Thirty-Eight Maps) and
Good Night, and Good Luck is the more-cheerful than it sounds remix of another celli classic, the Five Things
Five Ways Dan and Casey Signed Off From Sports Night on Various Occasions.
The five things story really won't make much sense unless you read the original; Alongside could be read as a stand-alone, but do yourself a favor and read celli's Prequel: it's short and masterful.
