Last matches at each Grand Slam between past champions - 3 of 4 involve Federer

[McEnroeisanartist]

I was wondering when the last matches between the previous (2 most recent) champions at each Grand Slam were:

For example: at the 2016 US Open, if Djokovic (2015 US Open champion) played Cilic (2014 US Open champion)

2015 Australian Open - Djokovic (2013 champion) defeated Wawrinka (2014 champion)
2011 French Open - Nadal (2010 champion) defeated Federer (2009 champion)
2005 Wimbledon - Federer (2003-2004 champion) defeated Hewitt (2002 champion)
2007 US Open - Federer (2004-2006 champion) defeated Roddick (2003 champion)
