As part of my personal practice routine, I select somewhat challenging and interesting recordings to play along with that I don't normally get to play with others.
The other day, I selected Won't Get Fooled Again.
About half way through - right before the drum / keyboard interlude - a tiny spider descended out of nowhere on a thin strand of web and proceeded to dangle in mid-air beside my right forearm.
Needless to say, this distracted me enough to disrupt my timing for the remainder of the tune.
