I've been working on a collection of Beatles-related activities http://www.esllistening.org/beatles/home.html including a webquest http://www.esllistening.org/beatles/beatles/webquest.html.

I've reworked the materials for younger learners (11+) here: http://younglearners.eslreading.org/beatles/beatles/webquest.html

It's been an epic task and I'd appreciate feedback, particularly regarding typos, broken links and any other glitches.
