Comment from said friend -

"I'm now getting used to the layout of the Lyrics and Knowledge page, but
wonder, why, when I tab through the alternative texts for the links do I get
a series of meaningful ones like
"Cleckheaton Festival", "anyone know about Jack Roland", and then one with a
number, e.g. "169"? After one of these numbers, the next alt. tag listed is
always "D". What's all that about?"

and I add my own comment - did this or the accessibility thread not at one stage become permathreads? I have had to "search" to find this...
