Thanx folkies.
I have added a search page based on HTML5 so older browsers will not cope. some say Firefox 21 onwards (eg) copes, but searching for a comparison chart is not revealing which browsers &/or version support <button> and <audio> TAGs
Any help would be instructive.

if you use the test page - try looking for "courting" and click the display button - they have possibly more general (& salacious in some instances) interest.

Next up I will venture to the HTML5 (& drop down to Flash if necessary) player. Meanwhile TIA for any comment.
