Anyhoo, she was singing (lip-synching?) into a mic, while riding around on a flying prop that looked like an enormous hot dog. And, waving a rainbow flag.

She is young, and last time I saw a picture, she had short, blonde hair ... so that must have been she. We were watching “Michael Palin’s Full Circle” on DVD last night. He went to Chile and Bolivia.
