*F2 = an F chord played with the first finger on the second fret (so when the capo 
is on 5, the F chord begins at 7).  I'm not entirely sure what chord this is, but 
I believe technically it's a G

The ornament at the beginning played with "what would you say to marriage" starts 
at C, them moves up to F2 with these three notes:

e  | -------------------3--1-- | 
B  | --1----------------3--1-- | 
G  | -------------------4--2-- | 
D  | --2-----0--2--3----5--3-- | 
A  | --3---------------------- | 
E  | ------------------------- |
