Greenawalt plays ukulele and Barratt contributes on a variety of different instruments. The pair is publishing their work on their blog, Roger & Dave Present The Beatles Complete on Ukulele, reports the Telegraph. They are also producing each song and making one available to download every Tuesday.
For the first instalment of the project, the pair released a cover of 'While My Guitar Gently Weeps" performed by Dandelion Wine, a New York-based group, in January 2009. Since then they have extended their list of covers to 71 songs, including 'Yellow Submarine", 'Hey Jude" and the latest entry, 'Nowhere Man", sung by Emily Bindiger.
Each entry on the blog also contains a commentary on the song, detailing the history behind it and analysing the music and lyrics. The next cover will be 'I've just Seen A Face", performed by Mumtaz Jefri, on June 8, with a number of hits including 'Michelle", 'Strawberry Fields Forever" and 'Help" to follow later this year.
The project is scheduled to finish on July 31, 2012, the eve of the London Olympics, with a cover of 'The End", to be performed by 'Everybody".
