Tonight's the Night

I was just looking on Google Images for photos of spawning salmon; yesterday in one of those synapse-twitching epiphanies I linked my early memories of an over-made-up Rod Stewart on Top of the Pops with the scary pics of spawning salmon I saw on a documentary once. I couldn't find a photo that matched Rod in all his colourful glory, unforchly.
The next train of thought was Rod's song 'Tonight's the Night'
I do love a lot of Rod's stuff and I love his voice, but I remember the petrifyng thought at the time of being 'tonight's the nighted' by Rod.
Yuk.
