Well now, here's a rather interesting story about Roy Rogers and Trigger. Not for the faint-hearted... told to me by an old guitarist mate who was a close friend of the sax player (who saw it happen) who told it to him...

Roy and Trigger were booked to play at a major London theatre, and the sax player had a mate - a violin player, a drinking man, who was booked by a well-known agency to play in Roy's backing band.

The backing band were in the wings, hidden from the audience, playing for Roy. Also in the wings was Trigger, taking up a lot of space and getting in the way of the musicians. The finale was to be Roy whistling for Trigger, who would come on stage from the wings - Roy would jump on his back - and Trigger would do the famous rearing up on hind legs business.

The violin player, slightly drunk, was sitting right next to Trigger and getting more and more fed up with this great beast next to him. So, he aimed his violin bow in such a way that the end kept tickling Trigger's balls - and kept tickling Trigger's balls... Came the finale. Roy whistled for Trigger. Trigger came on stage. Roy leaped on Trigger. Triggers reared up as usual - displaying an immense Trigger cock to the consternation and amusement of the audience, and the bewilderment of Roy.

The band fell into hysterics, the violin player never worked for that agency again.
