Mine is dire straits, on every street.
When ddad told us he had cancer we left shortly afterwards and this came on in the car. Dad is a huge dire straits fan and this song just made me think of him, and how if he wasn't around I'd 'see' him on the street.
Morbidly, I decided it would be played at his funeral. Luckily I haven't had to break it put yet. But the first few bars have me in floods of tears.
