The first guitar Sir Paul McCartney ever played will go under the hammer in London later this month (JUL06). The former beatle learned his first chords aged 15 on his friend IAN JAMES' Rex acoustic, and it is expected to fetch $180,000 (GBP100,000) at London's Abbey Road studios on 28 July (06). A letter of authenticity written by MCCartney reads, "The above guitar is the first I ever held."
