Love the Carpenters God bless 'em but cringe when I hear this one:
Carpenters - Goodbye To Love - YouTube
That's funny, usually people go out of their way to praise that solo (two solos, really, with the outro), not despise it.
The music in your link sounds weird-- like two versions layered on top of each other? The studio version is just one guitar, through a Big Muff or some other sort of 70s fuzz pedal.
I always kind of liked that solo. Tuneful and musical, and I smile at the way the Carpenters thought they were being "out there" by putting a fuzzy guitar on one of their ballads.
