Here is a nice line from when McCoy was younger and recorded an all Ellington album. In this line McCoy is beginning to develop his sound using his pentatonics but it is definitely not as pronounced as when he is recording with Trane and by himself a some years later. This is a great line to get you started with the pentatonic patterns. It takes a while for the fingers to get used to these patterns, practice the groupings of pentatonics. Enjoy!
