Stuck on
1. Well maybe, perhaps 2/3 letters
53. Seen on a poster as required 6/7 letters
69. They're seen but they're not there 7/8 letters
Any help appreciated. Thanks.

1. If?

53 wanted?

[factor-fiction]

We are looking for are song titles -top 10 hits.
Can you remind us of the range of initial possible starting letters please.
Children has been suggested for 60 but I'd have thought the clue should say "not heard" rather than "not there"

[factor-fiction]

Wanted by The Dooleys is a good answer for 53

[vakayu]

Thank you for clarifying that factor,op did not say it was top ten singles!!

[vakayu]

Gee lucky first guess,and I didn't even know.

Factor-fiction 53 Wanted sounds great. Many thanks. I wondered about If for 1 but wasn't sure it really fitted. Hadn't thought of Visions for 69 thanks Frank97. This had been a great quiz so will be interested to see the correct answers.
