Any iPhone / iPad users? New app out, This Day in Led Zeppelin. The app lists every gig the band ever played, has a Zeppelin quiz with hundreds of interactive quiz questions, scored out of 10, (which is very good!) and loads of Zeppelin trivia. Also it has detailed song notes of every studio track and every Zeppelin album. The cleaver bit is, the app plays your Zeppelin songs from your iTunes while you read the song notes. iTunes link: http://itunes.apple.com/us/app/this-day-in-led-zeppelin/id414461191?mt=8&ls=1 Any other apps you want to recommend?
