Putting the blog to bed. Good night: Jimmy McCulloch

...McCulloch [ at age 15]  first rose to fame in 1969 when he joined Pete Townshend's friends, Andy 'Thunderclap' Newman (piano) and songwriter John 'Speedy' Keen (vocals, drums), to form the band Thunderclap Newman. The band enjoyed a UK #1 hit with Something in the Air that year. Thanks to "Something In The Air", McCulloch is the youngest person to date to have performed on a number one hit song in the U.K. Thunderclap Newman's album, Hollywood Dream, on which McCulloch's titular instrumental then and his song "I See It All" later appeared, sold well but was not as successful as their hit single. From January 1971 until mid-April 1971, the band had toured England, Scotland, Holland, and Scandinavia before they disbanded in late April of that year. [...]
McCulloch is the kid wearing the shirt with a star on it.

...In 1973, [at age 20] McCulloch played guitar on John Keen's album, Previous Convictions, had a brief stint in Blue and he played guitar on Brian Joseph Friel's debut album under the pseudonym 'The Phantom' before he joined Wings in April 1974. McCulloch's debut track with Wings was "Junior's Farm".

McCulloch composed the music score of the anti-drug song "Medicine Jar" on [Paul McCartney and] Wings' Venus and Mars album and the similar "Wino Junko" on the band's Wings at the Speed of Sound album. Colin Allen, former drummer for Stone The Crows, wrote the lyrics of both songs.

Here's 21 year old Jimmy McCulloch's debut track as Wings lead guitarist:

Here's 22 year old McCulloch performing his composition "Medicine Jar" while touring with Paul McCartney and Wings in 1975. He should have heeded his own warning.
McCulloch died of heart failure caused by a heroin overdose on 27 September 1979 in his flat in Maida Vale, North West London. He was 26.
