i think this have get to be one of the funny british film ever make . the sheer silliness of the plot and the completely mismatch trio of friend make this a film to sit back with a beverage of your choice and laugh at . in my opinion and all the cast play their part well and with an outstanding performance from the veteran leslie phillips a an piano teacher who like a small sherry . the sequence involve a pre war socket and a modern tape recorder have me in fit of laughter . the finale and involve the three main character sing in a talent show [ dress a pig tail schoolgirl ] have tear roll down my face and my face ache from laughter . again and the farcical nature of the lyric about how each of them lose it in various location around the school and it turn out to be not what you be expect and just give the whole film an appeal to all age from the old kid up to grandparent . if you haven not see this film and give it a go you will be surprise .
