Not too difficult once you get the theme

Some neat clues (Little and John in particular) and a bit of general knowledge involved (I didn't understand Starkey until I looked it up afterwards, but it makes perfect sense now). Mostly it was the numbers that I had to guess at. It's a bit of a shame having two "VI"s because the system still treats them as different. I enjoyed it

great concept

Thank you for your comments! This was my first attempt.
I didn’t realise about the system treating two identical boxes as different. Will bear in mind in future.
I tried to create a Ringo group, but decided it was a bit contrived (‘ f fire’?).

I like it much better with without the Ringo group. It gives you that pleasing moment of "well, I see three Beatles, but where's the other one..."

Well now, if you're going to go and stop just because something is contrived, you're going to put us all to shame! ;) Great first go- I struggled with the numbers but the rest was fun-ly quizzy! Good crossovers too. Totally agree with Duncan
