Back to Klook: His debut as a leader were four sides for Swedish Odeon, recorded during a stay of the Edgar Hayes band in Stockholm on March 8, 1938. They were included on the "Special Kenny Clarke" CD of the French EMI Jazz Time series (# 46), and on the second Chronological Classics CD of Edgar Hayes, 1938-1948 - EKE BBB didn't list them as they were under Clarke's name.
