I find, when dancing the one or two dances I’ve danced that try to steal the Dublin Bay figure, they have a line backing up bending into a circle. I found this transition not to my taste. So I took a stab at a different transition. I think it works, but it’s a bit tricky:
 
Happy Birthday, Susan
Erik Hoffman
Becket
A1      Wm “Chain the line” (Wm Al R ¾, then to next Wm,  Al L ¾ to meet Nb on R diag –  across from Shadow);
Neighbor Swing
A2      LLF&B;  Wm Chain to Shadow
B1      Dublin Bay DH4inL ends loop back, centers step forward to
B2      Pt B&S
 
Given to Susan Petrick on her birthday, while on tour with the OpporTunists in 2010 (I think).
        The Dublin Bay DH4inL: Down for 4, turn alone backing up for 4, up for 4, turn alone, backing up for 4. From the ECD dance Dublin Bay. Others have used the Dublin Bay  move, but ended it with a “fold into a circle. That backing up, then circling has never felt good to me. This is my attempt to come up with a segue I like.
        Note, even though it’s a Becket dance, there is a difference in roles in this dance between the “ones” and “twos”.
