[Tex/LaTex] \centering doesn’t seem to center the text

horizontal alignment

I am trying to center this page but it will not work. All is get is for the first line to be indented about one "tab" space to the right, but the second line will not shift. However, the first line's indent does not appear to be centered either. Is it possible that the binding offset or the indentfirst package is interacting with this negatively? All of the other pages seem to work just fine.
Any help would be appreciated.

\documentclass[12pt, a4paper, twoside]{article}
\usepackage[margin=1in,bindingoffset=15.5mm,heightrounded]{geometry}
\usepackage[T1]{fontenc}
\usepackage{indentfirst}
\begin{document}
\pagestyle{empty}
\vspace*{36 pt}
{\centering
\textbf{\emph{\Huge{Since I Saw You Last,\\There's a Change Upon You}}}
}
\end{document}

\documentclass[12pt, a4paper, twoside]{article}
\usepackage[margin=1in,bindingoffset=15.5mm,heightrounded]{geometry}
\usepackage[T1]{fontenc}
\usepackage{indentfirst}
\begin{document}
\pagestyle{empty}
\vspace*{36 pt}
\begin{center}\Huge\bfseries\itshape
Since I Saw You Last,\\There's a Change Upon You
\end{center}
\end{document}

Note that \centering and size change commands such as \Huge should always be used in a way that the end of paragraph is in scope of the command, otherwise you will get Huge text on a normal sized baseline, and inconsistent spacing. \Huge does not take an argument it is just \Huge not \Huge{.....}.
