Hi guys. I have a text file that looks like 
January 1, 1915      Franck Pourcel
January 3, 1926     George Martin
January 3, 1945     Stephen Stills
January 3, 1946     John Paul Jones
January 4, 1942     John McLaughlin
January 5, 1950     Chris Stein

And I want to replace it with 
January 1, 1915      (Birthday) Franck Pourcel - singer
January 3, 1926     (Birthday) George Martin - singer
January 3, 1945     (Birthday) Stephen Stills - singer
January 3, 1946     (Birthday) John Paul Jones - singer
January 4, 1942     (Birthday) John McLaughlin - singer
January 5, 1950     (Birthday) Chris Stein - singer

Sometimes the spaces after the year are less or more.

This is what I got so far. 

#!/usr/bin/perl

use warnings;
use strict;

open(LOG, "source.txt") or die "error";
my @lines = <LOG>;
close(LOG);

my $cnt = 0;
foreach my $line (@lines)
{
  $cnt++;
  $line =~ s/(\d+\s+)(.+)/$1
  
}

I think I need some help.
