1972 - Martin Carthy singing "Skewball"
1972 - Maddy Prior singing "Wee Weaver"
1974 - The Songwainers singing "Bright Phoebus" and "Holland's Leaguer"
.....
1997 - June Tabor singing Bogle's "And The Band Played Waltzing matilda". My skull and face went numb, I nearly had a stroke. Later I just cried uncontrollably. No better song and no better singer in my book.
2001 - Bob Fox singing "From Clare to Here" and "Big River"

Nutty, thanks for the accolade. But time doesn't flow as fast as that - The Flowers & The Guns was written in August 2002, so you must have heard it at "your" Song & Ale the following winter.
