Whilst not strictly on the theme of unusual musical requests, I have played for a couple of funerals where the local Constabulary was out in force.
In one case it was the funeral of “ The Chief Executive” of a mobile tarmacking firm. The precession to the cemetery being escorted front and rear by tarmac wagons – with several police cars at a discrete distance .
In another, the sons of the deceased had to sit on opposite sides of the church in case things kicked off. Both sons being heavily restrained, handcuffed to two officers each and completely surrounded by members of prison staff and the local constabulary.
Playing for a wedding at a packed church, people standing round the console and other leaning against it, I overheard one young lady say to her intended “ When we get married we aint ‘avvin no ‘imms, cos no-one heffing sings ’em” – charming !
