Whose Song?

I genuinely know little about birds, especially their songs, and there's one I keep hearing but all attempts on YouTube have failed to identify it. The only way I can describe it is that it sounds like tickety boo (or at least the rhythm is the same). Is this familiar to anyone?

@wild edges I'm pretty sure there's not much chance of finding the bird, there's a lot of very big trees in my vincinity. There's an abundance of sparrows, dunnocks and blackbirds in my garden (pigeons don't count) but that's about it at the moment.
Alas the RSPB website didn't come up with anything.
I was beginning to wonder.....
This season is a topical " I've had me hair done" (we are Northerners) and an encouraging "Take your time" as I am working on something.....
The wood pigeons "We don't like custard....we don't like custard.....we don't like custard....NO!" was getting a bit repetitive until recently, when it changed to "We don't like rugby league....we don't like rugby league.....".etc.
Not an answer to your question, but a lovely hour of relaxing birdsong to listen to.
If you live in Derbyshire, as I do.
