I like this song, but I wish it didn’t start with ‘La la la.’ Just seems a bit unimaginative. It was written by Pete Townshend for the Merseys, who released it in July 1966. It was produced by Townshend though the label credits Kit Lambert. It did not get into the charts.
The Who recorded it in October 1966 for their second album, A Quick One, which was released in December 1966.
Townshend also recorded a solo version in 1966, a fragment of which was released on his 1983 album Scoop.
Here is a live performance from 1967.
This is Townshend and Paul Weller in 2000.
Here are the Who in 2014, by which time they have taken my advice about the ‘La la la’ intro. This is at the Birmingham NEC on December 7, during their 50th anniversary tour.
