We are really, really sad and have "signature tunes" for each of our horses, which we chose on a long and boring car journey
... "Rave On (Rufus)" - Buddy Holly - for our lovely chap who tends to bounce a lot when he gets excited; the theme from "William Tell" for the ex-racehorse, 'cos its extremely fast and energetic, and "Once, Twice, Three Times a Lady" for the dreaded mare!
izzy's is "you are beautiful"(she falls asleep to that)
my old loan pony woody used to respond to "riding dirty" and if a youngster is scared or spooking it gets a good blast of baba black sheep
Definately the one that goes 'what's that coming over the hill - is it a monster...is it a monst -eer' used to sing it to my gelding who thhought there was a horse-osaurus behind every hedge just waiting to eat him...
