Want some good news about Aerosmith’s troubled tour? Dream On. The veteran rockers have officially postponed shows scheduled for Saturday in Tampa and Monday in Sunrise/Ft. Lauderdale, after a few days of confusion as to whether they would proceed. Seven shows have now been scrapped as a result of an unspecified leg injury suffered by 61-year-old singer Steven Tyler.

The trek kicked off on June 10 in St. Louis, and the band managed to perform seven shows through June 29 before Tyler (pictured left with guitarist Joe Perry at the American Music Awards last November) was hobbled. Initial sympathy expressed by fans on the official message board at Aeroforceone.com is now turning into frustration as they have to cancel travel and accommodation plans, babysitters and the like.

Perry’s Twitter messages did not help. He told fans on Wednesday that the shows in Florida would not go ahead, but then changed tack the following day saying there had been a misunderstanding.

The good news is that guitarist Brad Whitford, who was sidelined by a head injury just before the tour started, is ready to rejoin his bandmates once Tyler is back in the saddle. All eyes are now on the Atlanta show scheduled for Wednesday.

The band says the seven shows (so far) will be rescheduled but has not confirmed any details. Perry said on a Florida radio station Friday that he hoped to be back in October. Dates are on tap through Sept. 16 in Detroit.

Rocking out with Aerosmith can be hazardous for your health. Four out of five of the veteran group’s members have disclosed major medical problems in the last three years. The most recent addition to the sick list is guitarist Brad Whitford. 

The band’s publicist said on Monday that Whitford, 57, is recovering from “recent surgery,” and will miss an unspecified number of dates on the band’s tour, which begins on Wednesday in St. Louis. She declined to comment on Whitford’s ailment. Bobby Schneck, who has played with Green Day and Weezer, will fill in for him. 

Here’s an update on Whitford’s bandmates:
    - Singer Steven Tyler, 61, underwent throat surgery in 2006, forcing the band to cut short a tour. Tyler, who has long battled substance abuse, checked into rehab last May saying he wanted “a safe environment” to recover from a series of painful foot surgeries.
    - Guitarist Joe Perry, 58, was forced to undergo emergency knee surgery earlier this year after developing “unforeseen complications” with a replacement knee.
    - Bassist Tom Hamilton, 57, underwent a seven-week course of radiation treatment for throat cancer in 2006.

That leaves drummer Joey Kramer, 58, who famously set himself and his Ferrari on fire at a Boston gas station in 1998. Later this month, he will release a memoir detailing his emotional breakdown in 1995 and his battles with depression and anxiety.

Of course, Aerosmith’s members are lucky to be alive after their hard-partying heyday in the 1970s, when they ruled the charts with tunes like “Dream On” and ”Walk This Way.” Since regrouping in the late 1980s with the help of drug counselors, they have largely kept to the straight and narrow. They have slowly been recording their first album of new material since 2001’s “Just Push Play,” but there is no word on a release date.
