The WHO, a British musical aggregation with its own special brand of pop sound, a wardrobe more “out” than mod, and an instrument-smashing concert format, will appear here at two shows, at 7 p.m. and at 9 p.m. Tuesday at the Mosque.

Another popular English foursome, The Troggs, will share the musical chores.

The four men known as The WHO all stem from a tough area of London, a district known as Shepherds Bush, where most boys would sooner join a street gang than be caught playing the guitar.

However, the four, who share a distaste for any sound that is not in rebellion against what is currently acceptable, joined together and within a short time became popular with the young set in rebellion against everything else. Starting with rhythm and blues, adding their own ideas, writing their own songs and arrangements, the youngsters quickly hit the big time.

Their first original, “I Can’t Explain,” written by guitarist Peter Townshend, hit the top ten not only in England but all around the world when it was finally recorded.

Since the 1965 success of “I Can’t Explain” the WHO have turned out a succession of hit records. “Happy Jack,” a record that is really an entire radio show, including songs, commercial take-offs and crazy patter, was released in 1967 to coincide with their first American appearance and proved to be a major hit here. It was followed by “Pictures of Lily,” which also got a big play.

The Troggs have recently had the song in the top spot on the record charts, “Love Is All Around,” and are also known for “Wild Thing,” “With a Girl Like You,” and their current hit, “You Can Cry If You Want To.”

The Troggs, a more conventionally sounding and slightly less startlingly dressed group than the Who, nevertheless have a strong popular appeal.
