The two surviving members of The Who are planning to record a new album under the working title Who2.
Townsend is writing his autobiography
Pete Townshend said on his website that he and Roger Daltrey were recording in December for a possible spring release.
"If the recording works out we will tour with the usual band in the first half of 2005," wrote Townshend.
Townshend is also working on his autobiography, started in the wake of his police caution for accessing child pornography websites.
"My autobiography now offers me the chance to lay down my life story and place recent events in proper context," he said.
"I have had a long and lumbering life -- this book will take time."
Townshend and Daltrey have been working on new material since 2002 and released several songs on the Geffen compilation Then and Now.
Original Who member John Entwistle died in Las Vegas on the eve of The Who's US tour in 2002.
