Old Macdonald Had a Farm Preston Guild Hall

Saw this show with my 4 and 6 year old grandkids today. It cost me £25.50 and I thought it was rubbish. It lasted about an hour in spite of being advertised as 75 mins. Two cast members, one had a terrible Devon accent and the other a bad fake Russian accent, making it very hard for the kids to understand. A few amateurish props and a singalong that I could have done better myself. As a retired primary teacher I have probably seen more shows than most in schools and I thought this was an outrageous rip off. Would be interested to hear what other grans think.
