Prog rock band wanting second album to sound like Howling Wolf? (4)
I believe the answer is:
yelp
'sound like howling wolf?' is the definition.
'yelp' can be an answer for 'sound' (I have seen 'Painful sound' mean 'yelp' so perhaps 'sound' could also mean 'yelp'). I am unsure of the 'like howling wolf?' bit.
'prog rock band wanting second album' is the wordplay.
'prog rock band' becomes 'Yes' (Yes are a progressive rock band).
'wanting' is a deletion indicator (wanting can mean lacking).
'second' becomes 's' (common abbreviation).
'album' becomes 'LP' (abbreviation for a long-play record).
'yes' with 's' taken out is 'ye'.
'ye'+'lp'='YELP'
'to' is the link.
Can you help me to learn more?
(Other definitions for yelp that I've seen before include "Shrill short cry of dog" , "Painful sound" , "(Eg, dog's) short cry of alarm" , "Squeal" , "bark sharply" .)
