This was a red letter morning.  I stumbled onto how to most easily find all the recordings posted on YouTube by any given contributor.  This will make it easy to gather a large collection of Bob's performances.  However there is one danger in this, which is that one must be very careful not to become a completist in making such a collection. Being a completist might be okay in some cases, but with Bob it could be a giant curse because there is such a gigantic quantity of material that one could find the collecting turning into an obsession to find it all and record it all.  This could become a mind numbing activity that could kill off the joy of finding and saving a large number of treasures.  It is very important to capture the joy and spontaneity in his work.
