Oysterband - 20th April which I have learned just now is a cover
The chorus is in Spanish and goes like this
¿recuerdas aquella noche en la cabana del Turme?
las risas que nos haciamos antes todos juntos
hoy no queda casi nadie de los de antes
y los que hay han cambiado, han cambiado …
[do you remember that night in the hut at Turmo's?
the laughs we had then, all together…
now there's almost no one left around from those days
and the ones that are have changed, they've changed…]
