[Tex/LaTex] how to stop Extrainfo appearing in cover letter

Question

I am using Texmaker to update my CV, but i am having problem with the \extrainfo. I am using moderncv documentclass and moderncvstyle {classic}. I want extrainfo to appear in my curriculum but not in my cover letter. Latex Template code is given below:

\documentclass[11pt,a4paper,sans]{moderncv}
\pagestyle{fancy}
\usepackage{moderntimeline}
\moderncvstyle{classic}
\moderncvcolor{green}
\usepackage[utf8]{inputenc}
\usepackage[scale=0.75]{geometry}
\name{John}{Doe}
\title{Resumé title} 
\address{street and number}{postcode city}{country}
\phone[mobile]{+1~(234)~567~890}
\phone[fixed]{+2~(345)~678~901}
\phone[fax]{+3~(456)~789~012}
\email{john@doe.org} 
\homepage{www.johndoe.com}
\extrainfo{additional information}
\photo[64pt][0.4pt]{picture}
\quote{Some quote}
\begin{document}
\makecvtitle

Then code goes on with section, subsections for CV until we arrive at the coverleter part

    \recipient{Company Recruitment team}{Company, Inc.\\123 somestreet\\some city}
    \date{January 01, 1984}
    \opening{Dear Sir or Madam,}
    \closing{Yours faithfully,}
    \enclosure[Attached]{curriculum vit\ae{}}  
    \makelettertitle
    \makeletterclosing
    \end{document}

What i get in Cv and cover letter is shown below:

Same 'Additional information' appear in the cover letter as:

Now I want to keep this Additional information in my Cv but want to remove it from the cover letter. Any help????

Answer 1

Instead of patching \makelettertitle, you can just set the "additional information" macro (\@extrainfo) to \relax:

\makeatletter
\let\@extrainfo\relax% Remove \@extrainfo
\makeatother
\makelettertitle
