Thrakbog, the boy band

I had a terrible nightmare. And I cannot possibly find words to express my relief that it wasn't real.
Here's what happened:
Last evening she-human and I had a lengthy discussion (no yelling, just plain talking) about different tastes in music and she told me about her fancying a boy group when she was a teenager. I had no idea what she meant so she showed me pictures and videoclips of several groups of young humans (presumably male, though I'm not so sure, and neither were they, obviously) in very colourful clothes and of questionable musical talent.
So far so good (or bad).

No flowers in MY hair. I'm bold.

I've been going through she-human's tin-music (everything human comes in tins, remember?) and laughed my ass off (not really, as it is massive and it would need more laughter than any lung could possibly hold in order to laugh it off), when I came upon something called 'Flower Power'. I mean, really?
