Happy Birthday to Paul McCartney! One of the greatest songwriters currently living today, the ex-Beatle celebrates his, are you ready, 70th birthday today!

McCartney, who grew up in the unassuming town of Liverpool, England on June 18, 1942, went on to become of the most seminal figures of music in the 20th century, churning out a regular assembly line of memorable songs, spanning countless genres, beloved by fans globally, and covered by scores of musicians playing styles ranging from Arpeggio to Zydeco. It would take a book the size of a city’s telephone guide to explain the whole machinations of McCartney’s body of work and talents, and many scribes have attempted to put the man in biographical and critique form. One of the wealthiest musicians and biggest-selling ones of all time, the McCartney train shows no signs of slowing down or letting up even into the 21st century, as he still tours, performing Beatles songs and ones from his large body of solo work, still releasing albums, guesting on documentaries, charting new genres of music, this jack of all trades remains one of the greatest figures in musical history with his still youthful, whimsical, and witty zeal.

Today’s marks the birthday of Jimmy McCullough, the Scottish musician who pretty much played with a virtual who’s who of British rock and roll artists of the 1970s, but succumbed to a heroin overdose at the tender age of 26 and has been mainly forgotten about in today’s day and age.

McCullough is best remembered for his stint in Paul McCartney’s Wings from 1974 to 1977, playing lead guitar on many of their hits, including the number one singles “Listen to What the Man Said,” “Let em In,” and “Silly Love Songs.” He also played in a band prior to Wings, known as Thunderclap Newman, which is remembered for their song “Something in the Air,” (number one in the UK) which has been covered by artists such as Tom Petty, The Eurythmics, jazz impressario Herbie Mann, and Donald Fagen among others. McCullough was only 15 when he performed on that track, still holding the record for the youngest person to date to have performed on a number one single in the UK.
