Analysis of A drinking song

Come, brothers, share the fellowship
 We celebrate to-night;
There's grace of song on every lip
 And every heart is light!
But first, before our mentor chimes
 The hour of jubilee,
Let's drink a health to good old times,
 And good times yet to be!
       Clink, clink, clink!
       Merrily let us drink!
         There's store of wealth
         And more of health
       In every glass, we think.
       Clink, clink, clink!
       To fellowship we drink!
         And from the bowl
         No genial soul
       In such an hour can shrink.

And you, oh, friends from west and east
 And other foreign parts,
Come share the rapture of our feast,
 The love of loyal hearts;
And in the wassail that suspends
 All matters burthensome,
We 'll drink a health to good old friends
 And good friends yet to come.
       Clink, clink, clink!
       To fellowship we drink!
         And from the bowl
         No genial soul
       In such an hour will shrink.
       Clink, clink, clink!
       Merrily let us drink!
         There's fellowship
         In every sip
       Of friendship's brew, we think.
