Click on K for piano
This site has on piano:
Another One Bites the Dust
Bohemian Rhapsody
Dont Stop Me Now
Flash
Too Much Love Will Kill You
We Are The Champions and
We Will Rock You
To tell you the truth that is the easiest you'll get on the net. But it isnt hard to play some of the songs. I just started playing today and in a hour I learnt "Under Pressure" and "Another One Bites The Dust" by Queen and "Lucy In The Sky" and "You never give me your money" by the Beatles but if you would like some lessons link
could be a start
I have over 50 on my website. Also, there is a piano chord program, where you can click a chord name, e.g. "C Maj" and be shown how to play it.
There are also limited guitar chords on the site.
Enjoy !
