First Date writers Michael Weiner, Austin Winsberg and Alan Zachary join Playbill in the rehearsal studio for an exclusive preview of their musical, which begins previews July 9 at the Longacre Theatre. Songwriters Zachary and Weiner sing "First Impressions" — a duet sung by Zachary Levi and Krysta Rodriguez in the Broadway production — and the pair are joined by bookwriter Winsberg to talk about the musical and what inspired them to write it.
