Must admit I am as befuddled as everyone else...

Armed with the clue that the number 10 is important, I have been trying to fit the number 10 in with any of the clues and fear I may be going down a blind alley.
So I thought I would share my first thoughts in case it helps others or prompts Uncle Bob to give us more clues! [-o<
Bob Swiekert started the 1956 Indy 500 in 10th place and was the 10th winner of the Indy 500 in the Hulman/George AAA Sanctioning era...
Alfa Romeo won 10 Grand Prix (thanks to Fangio, Farina and Faglioli (shared).
Brabham Repco won 10 F1 races (8 Grand Prix and 2 non championship).
Jenson Button was the 10th British World Champion - but that would make Lewis the 9th, not number 11 as Bob taunted us with...
Am I in any way on the right lines? Pray tell... [-o<
Must go and lie down now. Brain hurts!
