hi, there was a post in which the strumming pattern for roobaroo was given. According to me, the exact strumming is as follows: d d D dudu D dudu u have to strum hard at capital D's.
If you listen to the song carefully it sounds like the strumming pattern is a couplet - you've got one of the lines pl do tryo do the other too.
just uploaded audio of my strum https://indianguitartabs.com/showthread.php?p=278728#post278728 waiting for better patterns. thx
