Led Zeppelin stays mum on reunion tour

Don't expect rockers Led Zeppelin to take their show on the road, despite having a sold-out reunion concert in London. E! Online reports only singer Robert Plant will be touring Europe in May, along with Allison Krauss, to promote her album "Raising Sand," on which he collaborated.

Plant and Krauss will begin touring May 5 in Birmingham, England. They will then continue on to Germany, Belgium, France, the Netherlands, Sweden and Norway.

Plant comes off a one-night only performance with his fellow band mates, Jimmy Page and John Paul Jones, in London's O2 arena. According to event officials, more than 20 million fans entered a lottery for 16,000 tickets to Monday's show. Rumors quickly spread that the band would soon launch a reunion tour, including a headlining performance at theBonnaroo festival in Tennessee in June, reports E!

The band, however, has made no official announcement, and Plant has voiced his objections to any reunion tour.

Led Zeppelin also saw an increase in radio play in the past two weeks. According to MediaBase, the band saw a 15.1 percent rise in airplay with 4,139 spins recorded Monday and Tuesday, up from 3,514 the week prior.
