Those are interesting comments about the music rights affecting whether something is released on DVD. However, in Peter Gunn (1958-1960), there were also songs in episodes, very similar to Hawaiian Eye, and I don't think this caused any problems. In fact, Peter Gunn (see my WWW site, http://www.petergunn.tv) was released on DVD by Timeless Media Group, kind of a low-budget outfit which has put out many classic TV shows. Some of the Gunn shows are now public domain, and may have become so in certain jurisdictions. There is also the Henry Mancini music on Peter Gunn, which has been released on CDs of questionable legality and quality, again in certain jurisdictions. You can even listen to some of Mancini's musical releases from the late 50s and early 60s on Itunes and Amazon Music in presentations which are obviously bootlegs. I have seen the latter with totally crazy titles for the albums which make no sense.
