Changing one string can totally change the nature of a tuning. Here we take Csus2 and raise the 4th string back to D. The tuning is CGDGCD which can be confusing if thought of as a C tuning but if we regard the 5th string as the root the intervals are the same as DADGAD (missing the top string). So this tuning can be thought of a Gsus4 (just as DADGAD is Dsus4) i.e. a familiar tuning shifted over by one string. The tune is a beautiful lullaby from the Gaelic speaking Hebridean island of Barra.
