Here's a few additions to the list of songs using the 1-5-6-Pattern:
Black is Black (Los Bravos) - Here the 1-5-6-Pattern is combined with another frequent pattern that I would call 1-5-b7-Pattern. Usually the 1-5-6-Pattern is mainly used for major chords. The correspondent pattern for minor chords would be the 1-5-b7-Pattern.
Time Is Tight (Booker T. & The MG's) - Duck Dunn it again ;-)
Love Really Hurts without you (Billy Ocean) - Again the 1-5-6-Pattern and it's also interesting how the rhythmic patterns do resemble amongst the different songs.
