Note to Romeo and Juliet, 1.4.1: "What, shall this speech be spoke for our excuse?"

Romeo and Juliet,
Act 1, Scene 4, line 1.
this speech: i.e., a written speech. Apparently Romeo has in his hand piece of paper upon which is written a speech (which functions as an invitation) to introduce the "MASKERS," Romeo and his friends, Mercutio and Benvolio before they join Capulet's celebration, for if their real idenities were known, Romeo and his friends (all Montagues) would not be welcome.

Mercutio (Christian Cooke), Romeo (Douglas Booth) and Benvolio (Kodi Smit-McPhee)

Mercutio, Romeo and Benvolio
