Beamer: First (title and authors) frame repeated at the end

[Mariano Llamedo Soria]

Hi, just in case anyone knows how to put the same frame of title and authors
at the end of a presentation in Lyx.

Googling around, I found that Christian Bustamante had the same problem some
time ago ...

Hi all,

I'm using the beamer class and I need to repeat the first slide at the
end of presentation. In plain LaTeX one can do the following

\documentclass{beamer}
\title[Short title]{The title}

\author[Authors]{Author 1 \and Author 2}
\date{\today}
\begin{document}
\begin{frame}[label=firstframe]
\titlepage
\end{frame}
...
\againframe{firstframe}
\end{document}

Which uses the againframe command. The thing is, how can I label the

first slide for then use the againframe in LyX?
