Rainbow Charity Quiz - Seen But Not Heard.

[RAZ1981]

Thoroughly stumped on the remaining four. Any hints would be greatly appreciated, but please don't just give the answer, as I would prefer to work them out. Simply in need of a little nudge in the right direction, if possible.
All answers must contain at least one silent letter.

57: Painstaking passenger gets in the way. (12)
59: The crest presents a lofty problem. (7)
61: ..... sounds like a well-rewarded job is on track. Straight up! (5,4)
67: After forlorn hope had warning police were near and flew from the fire. (7)

Many thanks.

67 a bird in Greek mythology

57. You may walk along it.

[RAZ1981]

Thanks Cashier. I have been thinking of that for ages, but I can't make it fit cryptically.

[scorpiojo]

Google the meaning of the last 3 letters

[dannyk13]

67,one of the four letter words in the clue is an anagram.

59 I'm not 100% convinced but thinks of roosters
57 A long way to spell road!

[JJ109]

Sorry Danny -missed yours! (for 57)

[JJ109]

Forget my suggestion for 59 - its not going to be a "problem"
It has a silent letter and concerns crests and lofts, but isn't a problem!

[dannyk13]

jj, no problem, the more hints the better.

[JJ109]

61 I can think of an answer but only if you pronounce the first word with a Scottish? accent
Sherpa Mail ??

[dannyk13]

jj.61.I don't think you need a Scottish accent as in a normal pronunciation the second letter is silent.

[JJ109]

Thanks Danny - now I've reread the clue again it fits as stated. I was thinking cryptically and trying to make the first word sound like "not bad" whilst the actual job description works anyway!

[RAZ1981]

Thank you to all. Still baffled by 61, but it gives me something to work with. I had nothing previously, so it's very helpful.

61. Use one to check that your wallpaper hanging is accurate

[JJ109]

61 Wiggers - that is a better answer than mine!

[dannyk13]

61, first word sounds fruity.

[dannyk13]

jj, Hope we didn't send the OP wrong.

[RAZ1981]

Got it! Amazing, thank you. Great hint, Wiggers99. Only a couple left now. I think I'll attempt to unravel them on my own.

57. Another word for "painstaking" plus another word for passenger (think of a taxi passenger) and the whole word means "a way" (as in street, road etc
